Vbulletin upgrade

[Ibn-Khaldun]

Don't know whether it's something to do with the forum upgrade but in the social groups page I have options to leave from the group but also I can edit and delete groups that I created.
However, when I try to delete a group I created it says I don't have permission to do that.
So, do members have the permission to delete groups they created and the button is just buggy or they don't have the permission to do that?

Edit: Btw, I like that now I can see who currently are browsing the forum I'm on!
