think it would be nice to be able to see which alt belongs to which main w/o having to look @ each toons guild info.
I'm thinking something along the lines of the profession layout but instead it lists all main toons that will xpand (like xpanding a profession)
Now how would you go about that . . i think it would be something that the gm or proper rank could input
Upon joining you (the new inductee) would tick a little box next to your name as it would normally appear in the guild window that would highlight the status of the toon as "Main"
Upon bringing another toon into the guild you would once again be able to choose "Main" or "Alt"
Once you select "Alt" you would then be able to enter the name of your "Main" toon
