Hello all, I thought that I'd place the announcement here rather than on the forum, but if Sannse has a big problem with that I can change it...
I am pleased to announce that the customs wiki is now open to edit! Here it is!
There is still work to be done. It needs a logo, it needs a proper main page, and the images haven't been fully imported yet. However, it is ready for you to make pages and edit! Upload the images onto meta, otherwise you can only use them on the customs wiki and none of the other projects.
Right now, you'll need to make a new account (with the same username as on Brickipedia) to edit there. However, that only takes a couple of seconds longer than logging in anyway.
