Guild screen should show last used character

When players are offline, the guild screen should show their name as the last one they used. Some players in my guild have deleted their old characters since joining, but when they're offline their old names are shown. It's a bit of a hassle to get them all to leave and rejoin the guild for that too.
Plus we have a guy whose name the game had an error with when inviting, so he had to make a new character with a name that the game liked just so he could join, but it will always show his unused name when he's offline.

Agreed, but only if that character was deleted.
I actually think that you should either get kicked out of the guild automaticly upon deletion, yet that might be a bit harsh. So they might rather want to make a screen that'll ask which character you want as your main character to be in the guild after you delete the current main character.

Why? I don't understand what you're getting at.... people should be dissuaded from using more than one character?
