Ninja guild banks WHILE already in the guild.

Isn't the gold trackable as well through the log? Or are you saying that through a report or something like that. Because doesn't the log give the name of all withdrawls?

The Armory keeps track of more transactions, not exactly sure how or how many though.
If you try this you should look into that first, so the guild cannot just login to the armory and see what you've done.

If you want to do this I suggest trying it right before a maintenance, that might help to cover your tracks.

Using /gdisband might not remove eveything from the armory site right away,
but if you use it and then gather sigs for another guild with the same name it might really dick things up for whoever is trying to figure out what happened.
