You could probably make your own game. Just make sure you place what you are offering first. For EG, I wanted to trade away a Zod for a Jah. Or something like that. As for me, I'm a bit of a snake, and I find people who overpay, or I go to specific Rune trades.

zod 4 jah
Zod for Jah
Zod 4 hr
zod here
bring jah

Also, Squall, it is an open invitation, as SRL said. However, it's very much suggested that you have DSL or better. If not, it increases the lagtime, and the possibility that your game will become interrupted, which means you can end up losing hours and hours (or weeks) of work.

Also, SRL, do you have time to Cows/Rush me?
