Greg, I'll make this as clear as I know how:
If you're here to learn about motorcycling, feel free to use the entire site.
If you're planning on buying a bike soon, feel free to use the entire site.
If you think bikes are cool, but have no real intention of buying one, keep your use of the site limited to reading and asking the occasional question
about motorcycles.
If we allow anyone to come along and chatter about OT subjects, pretty soon the site becomes just another nondescript chat site that's paying server fees and requiring moderation for a bunch of useless drivel. We don't mind useless drivel, but it should come from motorcyclists (or intended motorcyclists).
