The the captcha has a back link, which can be removed, I guess, since its a GPL license, but why do I have dig?
It would be nice to be able to change the instructions/intro text, esp. since the English is not very good in the default text. (Sorry!)
It does work with a lot of different extensions, as listed in the plugin parameters. There are a lot of captcha options available now though, so I'm going to keep looking....
The downside for me is that it applies globally. i.e. Select a font for paragraph text, and the entire site changes. This is probably what a lot of people want, but for me, I'd like to see an editor button in the article editor to apply as and when. It does what it says....
Its not clear, if you select the option to sign up to a newsletter, how that request is handled. I guess you manually go and get the info and copy it over to your email system.
Clearly this extensions is in development, but the big problem for me is that you cannot remove the url field. It can be made required, or not, but can't be hidden. That means I'm going to be deleting links to pharmacies and who knows what. So not useable for me on that one point.
One to watch, probably.
In the lightbox to enter testimonials the text falls off the right side.
There is no capture.
When it refers to a "Button" - its really a text link, not a button. The appearance is very basic.
There's no uninstall. It sets itself up as a native Joomla! module, greyed out in the uninstall components list. I had to delete it from the module manager, and delete the files using ftp from 'modules' and /administrator/modules.
I know its free, but when you think about some of the offerings for free....
The only downside - and I couldn't find where else to post this - Hover doesn't work on a phone. With the increase of the mobile web, I would like to have captcha without having to hover over the captcha code before entering the numbers. Its the only thing stopping me using it on one website now.
Other than that, its my first choice for forms.
