Okay so an Idea just occurred to me that guild masters are not very well known, In fact the only way people know that you are the GM (guild master) is if they are in your guild...
so here is my suggestion: under your name, before your guild name, your have the word Guild master.
example:
Noxtus
guild master
the keepers
Its a very simple game mechanic that wont take much time to put in the game and is just a little perk for Guild masters..
It should also feature in the forums.
So what do you guys and gals think?
