Update: Here's the direct donation link if anyone else wants to chip in. They have just over 20k of the ~33k needed.

They have open registration last I checked, with an invite code available in the publicly accessible part of the forum (sorry, don't have a link right now, but probably they prefer you go directly there anyway).
