I agree with Hilly. Since we have the option, we should all be consistent with our tags. In order to have the "-bZ-" as our tags, it has to be part of our name. Otherwise, just inputting "bZ" into our profile results in "[bZ]".
Some members already made their names -bZ-NAME, while others of us had [bZ]NAME. Since we can change our names, it makes sense to keep it all the same.
As for recruits, they could certainly change their name to -bZr-NAME and drop the "r" when they become full fledged members.
