You do not have to have a Dreamwidth account to participate in Ante Up: The Losers Fic Exchange. Dreamwidth allows you to join, subscribe, and comment to community posts with Open ID. spn_bitesized has an excellent tutorial on how to set up and use Open ID to join and comment to Dreamwidth communities.

But if you'd like an invite code, the mods will be happy to provide one for you; comment to this post with the type of account you need (DW, AO3, or both), and the mods will reply to your comment with an invite code.

If you don't want to wait, here are a couple of other options.

If you need a Dreamwidth invite code:

• Comment to this post.
• Visit dw_codesharing and see if anyone has a code you can snag.
• Ante up $3 for one month's paid time.

If you need an AO3 account:

• Comment to this post.
• Visit Archive of Our Own and put your name and e-mail address in the queue. You'll get your invite code in short order, generally no longer than a week.
