Should have a logo contest.
As for the buy and sell I dont think it should be a bigdeal if you cant see the op location until youread ad. As braf said some/most are willingto.ship and some like myself post city within my headline.

A app other than taptalk would be cool
Also. R2R post alot of cool threads on there fb page this could bring alot more people to the site
