I must say this is one of the best scripts for Joomla I have come across. It is very easy to install, the authors provide excellent feedback in the forum (http://www.sigsiu.net/forum) and it has great features. SOBI2 is a fantastic full strength directory component system released for the Joomla CMS.
SOBI2 has plenty of features - I just keep finding new ones every week! The clean code, flexibility and power in SOBI2 are the perfect ingredients for a real web portal. Thanks to all the developers at Sigsiu.NET - well done! For anybody looking for a superb industrial strength Joomla directory extension - you've just found it.
