Sounds somewhat "complete BU"-ish to me. Maybe "BU-waypoints [at] gmail.com?" Something like that, which makes it clear that it's not an address that applies to all kind of BU-related stuff, only to the waypoint-site.
We might also choose a site name that can be abbreviated, just like Counter-Server Maps (CSM). Bots-United Waypoints? BUWP? Or WPBU? The account could then be named accordingly, like "BUWP [at] gmail.com"?
Or could we get a BU mail account so that the mail addy could be "waypoints [at] bots-united.com"?
Questions, questions...
