Thanks!

There's around 1k members right now. I stole the 10k catchphrase from The Listserve. Consider it aspirational!

Yes, people can be selected multiple times, but they must submit a post before they can be selected again.

No, I don't currently plan to release the posts. I might change that at some point but I'd want authors to opt in -- even though the license allows it without their consent I doubt everyone understands that.
