Very good idea, it would be a great help and theres also a lot you could add alot onto it such as who can and cant put fg into it, who can and cat take fg out, if other people outside the guild can donate fg to it. ( Reason for the last one is theres been times i wanted to donate to a guild and the only way is to send it to the leader.
Would be very nice and seems well thought out.
Voted yes, hope to see it added later on
