B33stly is an MFGGer who joined in the second half of 2009, around the time the phpBB boards opened. He claims to have joined MFGG before, but his old username remains unknown. He had "lurked" for quite some time.
B33stly spends most of his time in the General Chat and Forum Games section, the latter in which he participates in MFGG Football, MFGG Wrestling, and Baseball (which he coached). He doesn't appear to really be active any more, though, and hasn't posted since February 2010.
His avatars imply that he is a fan of the Mario and Luigi series.
He is currently preparing to coach the first ever MFGG Baseball team (although this wasn't really the first).
