The testimonials submittal form does not stop spam with either the included spam protection or recaptcha.
The developer, per his forum, knows about this since May 25, 2012.
I would not recommend using this extension until this is fixed. My site gets 20-30 spam emails per day. So I have to delete all the notification email and go in the backend and delete the hundreds of spam submittals in the extension.
Since the submittal form is a headache, I decided to just use a regular form for submittals and then past into an article. Looks the same without the hassle.
Its been over a year with no fix, so I had to assume its a dead extension.
Well in under 10 clicks I had a user group redirected to their specific community menu. There are 46 more communities but with such an easy UI this extension will make it painless.
One less thing for me to muck around with.
Its weird because all the back-end Save and Cancel buttons also "Close" the current screen, why would the front-end buttons not function the same?
According to the K2 forums, the developers have decided that this is not a bug but an "annoyance". Guess what is "annoying".... when you get a call from a client with Publisher permissions that see dozens of duplicate new items submitted for their review. I later figured out it is because the front-end editor doesn't know that his new item was saved because the screen does not close and there is not a confirmation. So he usually will try to resubmit the item again. Multiply that by dozens of editors clicking save over and over and over.... ouch! That's is not an "annoyance" that is a broken submission system.
The developer is easy to get in contact with via his forum and is very professional and knowledgable.
The plugin is constantly being updated with minor fixes and tweaks. I posted on his forum and within 1 day it evolved into a "feature request" and finally an update to the plugin. It now works with FJ related extensions.
