I don't believe the Description of each social group is suppose to be displayed like that. I believe vbulletin had released an update to fix that recently, but we never put our social groups back up on our site to figure it out. We had that problem on our site, but maybe that's how it's suppose to be now.
I'm sure you can go in a clean up the Description of your clan. We had it a bit different here, there was over 4000 clans in the old system that did not work well with vbulletin and we did our best to get them into the new vbulletin feature.
The clan section is good for us however how do we change moderator rights as i founded the Nùts clan however i would like to pass the moderator rights to someone else in the clan as i'm away alot? Help please.... is it possible?
