Installation and setup was very easy. It worked quite well right from the start, except that I had a little problem because i was using a custom register template. So i asked for help in the creator's forum, not really expecting something from it because most of those support forums are really just fake and spam.
But not in this case - i got help the same day and everything could be worked out and it works like a charm!

I think it's a way more user-friendly captcha than those indecipherable image captchas, and it has enough tweaking functions to set it up like you wanna.

Excellent plugin - Congrats to the author and keep up your good work and support!

I use the plugin for several extensions, which were previously always flooded with spam.

With EasyCalcCheck Plus I have not a single spam entry!

I thank the developers!

I was having a huge problem with spam in Phoca Guestbook. 100+ per week. Found this, installed it and stopped all spam completely!

Very nice, I even donated to the cause.

Thank you very much for creating this!

This is the perfect solution for anyone's anti-spam needs.

I was looking for a spam detector that would be effective, discrete in display, localized, and user-friendly (both for frontend and backend)

This extension fits all criteria. I don't like extravagant solutions, they don't match with a professional-looking website, and I dislike methods that are likely to be failed by users when utilizing the relative forms.
I run a greek website and it looks weird having adapted everything in the website, even urls, to to a greek target audience and have a verification system with distorted english words.

The solution provided by EasyCalcChecker Plus fits all the above criteria. On top of that, it is very versatile, supporting many different methods and services of spam prevention to choose from.

After install it was ready and up and running immediately. No hassling with setting and trial/error configuration. The extension is highly configurable and with straightforward settings, even for one who possesses no knowledge on the subject.

Another thing that sets it apart is the support it gets. I had one trouble with the "hidden field" showing up in my website, where I have the Global Cache option enabled.
The author responded immediately with a working solution, and responded to my questions very quickly.

There is nothing missing from this extension and it has the support needed to get it even further when other setting are needed in the future.

Very simple and easy to install. Using on two Virtuemart sites that had been plagued by product enquiry form spam. Took less than two minutes to install and configure on each, and spam has stopped. Excellent job.

This is really a well thought out spam protection extension. It uses multiple ways to help combat spam, which was a serious problem I had before with another website.

In addition, Viktor was most helpful in addressing specific issues I was running into. The template I'm using from RocketTheme was conflicting with his extension (RocketTheme templates use their own overrides, which creates formatting issues with this extension) and he helped tackle the issue for me, convincing me to switch from another spam protection tool.

I think if he wanted to added to add on a few more spam protection options, even if people don't use all of them, he could pretty much have the definitive spam protection tool here.

I want to translate the plugin in Greek(I would be happy to give you the files). I translated the ini file and put it in the el-GR language folder, but the translation doesn't seem to be working.

I wanted to use a captcha but avoid some of the images that throw people off. This is a nice alternative. Like a few other users I needed help getting it to work with a Rockettheme template. Viktor sent a file to me by email in less than a day. What more can you ask for.
Owner's reply

Some implementations of CAPTCHA takes several guesses to get it right, the image is just too difficult to figure out.

I reviewed a few different types of CAPTCHA offerings and having been highly frustrated with some of them, I knew what I was looking for. Something, easy and effective.

EasyCalcCheck PLUS is exactly that. It couldn't be easier to install and use immediately. Congratulations to the coder/s, you haven't over cooked it - much appreciated, many thanks.

It is nice to get away from those boring skewed letters and bring something 'intellectually' pleasing! As a newbie I just can say that it works flawless. I made a mistake and the author was quick and helpful to solve my stupidity in a very friendly way.

Thank you very much!

This plugins protects the registration and contact forms from spam by adding a small arithmetic problem, a hidden field and a time lock.

In Easybook Reloaded it is already installed. ;-)

after hours of research and finding a few outdated, very complicated registration form plugins for virtuemart, I got lucky enough to stumble onto this plugin.

Installed in a second and was working in 10 seconds.

I highly recommend.

Now I can comfortably inactivate user registration activation to make it much simpler for a buyer to buy something on virtuemart without having to get in their inbox to click an activation link.

This simple and accessible text based math captcha is exactly the thing that Joomla core user component is missing.

Great work guys!

I have been asking about this on the forum and waiting for someone to develop this for a long time. Finally it is here.

This is a great, accessible, text based math captcha.

Thank you,
