If you've stumbled across this without any idea what OTP22 is, don't fear; it's a long-running ARG from September of 2012.
The original community was on IRC and a forum called Unfiction, but a few months ago Unfiction suddenly disappeared and it doesn't look like it's coming back any time soon. Without any place to talk about it in longform, I made this, since it looks like there's a little life in the ARG again. It's been very quiet for a year.
If you want to know more, please check the resources and links thread. The top Unfiction thread has a very, very long writeup of the history and story behind this.
If you want to know how to help, well, right now, there isn't much to do.
