From HSOD:
We'll be taking submissions for NEW FANWORKS TO LICENSE here. Please feel free to submit! And as a funny little gift, we've gone ahead and bumped the amount of username messages up from 400 to 1000. Good luck finding them all, they're from all corners of the Homestuck world, from fanventures like AUTOPRAXIS & SBURB.EXE to some DANCESTOR STUFF from Befriendus. Good luck!
There's also a video.
