I definitely appreciate your tossing around ideas for a name for this site.
"Eight wheel united nation" is already a nice one, "Eight Wheelers Have More Fun" is indeed bad, but just because it doesn't nicely go into an acronym or something. Brian has a nice name, but that belongs to him. I'm often pusing something like 4trucks around my mind. OMA is a good one, it's very catchy. In Germany, there is even an OMSA. The Melbourne old school skaters call themselves MOSS. which is very nice.
