Are you talking about buying/selling on the HQ?
If so most of the time you have to build a relationship, sort of speak in order to be trusted.
People arent just going to send you money.
Paypal is a good choice bc they protect you, in the event that you do get scammed.
You can ship through usps,fed ex or ups, which ever you perfer.
If you are trying to sell something, take some pics, post the pics with a full description, price and location.
And more than likely you will get some bites.
I couldnt help but see in your sig, you saying your motor runs like crap.
who built it, where did you get the parts etc???
