After almost 2 months trying to find a good solution to make a directory of users, I found it [url=http://http://community.getk2.org/forum/topics/questionmember-and-user-group]Here[/url] in the old K2 Forum.

But the Title wasn't that easy to find so I decided to post it again.

The solution is this excellent extension to the K2:
Users View by Jiliko
NOTE: It needs to be uploaded by FTP and not installed through Joomla!

Also I needed it to work with SH404SEF, that HACK is here:
SH404SEF Plugin

Congratulations to the guys of Jiliko and hope that the K2 team will improve the component with this feature.

Hope it helps,
Felipe Oliveira

Hi Felipe,

Thx for the review...

Olivier, the guy(s) of Jiliko :-)

Olivier, does this extra view work with joomla 1.7?

We have followed the instructions, and do have the option "group" in the menu creation, but then, we have no parameters at all in the menu details, so we cannot select which group(s) to show.

Thanks
K.
