Just so you know, we're planning on the website's going live on Monday. Yay! Exact time to be determined; we're still getting our schedules coordinated. It's looking like midday in the US / evening in the UK / early Tuesday morning in Australia, but that might change a bit.
Once the website is live, you're welcome to post your story or art wherever you want. We'll get a collection set up on AO3 before Monday for anyone who wants to upload there. (And if you'd like an AO3 invite, please comment here with the e-mail address you'd like it sent to, and we'll see if we can get some more.)
Two more days! We hope you're as excited as we are!
