Changing the tab-info

Hey!
My newly created guild "Ambitions" is a merge with another guild within the game "World of Warcraft". My previous guild was called "Hets" and I'd thought I just re-use the old forum.
I was 99% done when I noticed the Tab in my browser still said this is "Hets - ICC Raiding Guild":

Spoiler:

I've checked all settings like 3 times and I still can't find the correct setting!!

Spoiler:

If a mod can change this manually, I'd like "Ambitions - Cataclysm Raiding Guild" @ http://ambitions.forumotion.com/


Thanks for help!
