I was planning to do one in October of this year (though now that it's been mentioned, I might wait till January as a more natural "census point").
If someone else wants to do one first, please get in contact with me so we can make it as similar to the last one as possible while also making the changes that we agreed were needed at the time.
Are you tentatively planning on January for the next census? I'm interested in helping, if that's something you need.
If it's worth saying, but not worth its own post, even in Discussion, it goes here.
