For example, we asked for a captcha and we got Re-captcha over the weekend. We asked for the user name to display after logging in and we got it within a day. Updated versions go up on their server all the time.
The software is extremely easy to install and use. There is an excellent guide with pictures and it took us only a few minutes to set our complex membership scheme and access control up. It works nicely with other Joomla extensions and we have not had a single problem that did not get addresses right away.
Well worth the money for these guys. They are on top of their software and really take care of their customers.
