Given the increasing number of forum users, and the difficulty for newcomers without a social network of getting input on their posts, I thought I'd highlight this Facebook group (I have no affiliation to it, if that matters for a FB group).
It doesn't look very active, but I think if you post an open-access Google doc in there, many people will still receive a notification about it and potentially read your work.
I think there's some kind of network effect? It's more attractive to post there the more people post there. Such things are hard to get going, and maybe need constant input. Maybe you could ask someone on the EAAnywhere channel Jeroen mentioned to pin a comment linking to it/add it to the description.
