It's no secret that I intend to go to Worldcon 2003. I'm saving up for it, but the World Science Fiction convention will cost a lot for me. Every person who signs up to Ebay through me will help me to afford this event.
I already have an account myself. As soon as I can get my scanner installed again here, I have a box of Dragon magazines to sell through there.
