Well, there is! rat_jam - the online companion to muskratjamboree.
rat_jam is an online event which will be held from March 29th to April 1st.
There will be meta! There will be fic, icons and art! There will be a screening party! And this is for multiple fandoms! You can come and go as you please!
I am so excited about this, I'm completely abusing the exclamation mark!
Join the community, because there will be locked posts with content you need to see. Go contribute meta ideas and fic/art/icons prompts. Come vote for what you want to watch at the screening party. And clear off your schedule, because there's nothing as fun as fans doing fannish things with other fans!
