Hi,
I have recently been wanting to do this getting ranked once registered feature...
I remember that on a server called DeltaGamers (No Longer Up) had this feature. I thought it was a nice little feature so that Operators ect didn't have to rank them manually or if they weren't online they'd be stuck as a guest 'till a person with the right permissions could rank them...
I am wanting to do this for my server, XaneGaming.com Lava Survival, since it would be easier for me and my staff members.
My website is run my Joomla if that helps at all, and believe it or not, it looks like this site for some reason...
Hope you guys can help
