Tested J 2.5 works great ..
Auto Redirection to your Main Joomla Site , Jomsocial, Kuena, Agora or any 3rd party joomla extension ..pretty much anywhere on your site with a powerful option of entering URL.
You can even redirect users to Non-Joomla CMS , Non SQL + PHP parts of your site to just plain HTML/CSS pages.
Or redirect to any self made PHP/SQL plugin/component/module of your own on your site that pulls your users from the joomla user table and they will be logged into that software !!
Excellent plugin, good to see developers keeping up the pace with J 2.5 extensions.
10 out of 10 :)
