Ok, so my friend is definitely doing Vriska, and I'm now doing Feferi. We've rounded up friends who are doing Nepeta and Sollux too. Also, for the Friday night rave, my friend is trying to round up people for Ravestuck. Here's a link for if anyone is interested; http://www.facebook.com/events/245015532245366/
We'd just meet up and hour before the rave to hang out and wait for it to open, and then go in and have some fun! Any character is welcome, and proper con/rave etiquette is expected, of course.
