When the new guild system came in our abbreviation got messed up. It used to be }-> and because you can't use > anymore it got changed to }-& which means absolutely nothing to us *frowns*. The only way to change it to something else (although we
really want our old one back) would be to delete the guild and reform it..losing all of our history!! That was just unacceptable to us so we live with our meaningless abbreviation
Being able to change the abbreviation without losing all of the old member names sounds like a great idea to me!
