I have added a profile area for swaps. Each member needs to fill it out before they can continue.
Go to the swap page:
Click on our swap, and then at the top, click on:
"Manage your swap profile"
You must fill in your address, so the host knows where to return your seeds to you.
You can also optionally add a infobox. You can type whatever you want into that field, and then later when people are viewing the main tradelist, if they select your name from the list, they will see your infobox at the top of that page.
