Please, be smart. The overwhelming majority of ticket sellers do not read the tickets wanted board. Sure, some do, but it's a very small percentage of the people with tickets to sell. You're welcome to post in here if you really want to, but the smart thing to do is to go where the tickets are.
Go read the TICKETS OFFERED board. If you see a ticket offer that you're interested in, SEND THE SELLER A PRIVATE MESSAGE (and make sure that message includes your contact info). Sure, you can reply in the thread, but that should be something you do after sending the thread-starter a private message. Really.
