I originally setup a classified section, but I found it much easier just to add for sale items to a thread in the forums here... You will get more views.
So, I would recommend posting a couple photos of your board for sale, and giving a price to go with. You will get responses if you are giving a good deal. You can ask people to contact you through private message on Swellinfo or by email.
thanks everyone. im looking to get around $400 for the fish. and it is on craigslist - im not having much luck which is why i am trying here. i can email pics upon request.
