Glad to hear you got the perfect idea
and to the guys that are wanting there bikes in the banner i sugguset that the admins do a bike of the month (was on another forum that does that)
The would take 4 to 5 bikes that all fall into the same catergory stock, custom, slighty modified, and anyother things that they can think of. It would be them searching through the gallery to find that bike and posting them in a poll and have other users vote on which bike they like best for the catergory.
Also it would have to be a nice background something from your favorite riding spot not your garage on stands in the middle of a project unless that becomes a cateragory best build pics
Just my two cents
