Neh. I don't much like this idea; seems rather pointless, since it really isn't all that hard to find a specific player on the Users Online, and I would prefer to have privacy. If it did end up coming into existence, I'd at least want to be able to make it not appear on my profile at all, similar to the optional AIM and MSN and dA things, which don't show up if you don't want them to. If it was always and unchangingly there, it would just be another little thing clogging up the '[user]'s Account' module on people's profiles - and I like my un-clogginess.
