FWIW, there are a couple of Stargate related Discord groups that are fairly active right now and most of those folk are not on DW... They do post on AO3 regularly, so that's one thing we all have in common.

When you're ready, I'll be glad to post info on your smaller challenge thing on their Discords to help get more participation.

One of the Discord groups already does regular watch parties. If someone wants to join in, I can see about sharing a Discord invite.
