There's a difference between announcing something (e.g. putting it in the post title or having a separate announcement, like was originally made when the rewatch thread started) and assuming people will infer it from the days you post.
The rewatch was originally proposed for Sundays; switched to Mondays; and then switched again when you took over.
And even that's different from what I'm talking about: I reviewed the threads out of curiosity, and while the original proposal (3 years ago) talked about people watching it at the same time, the current rewatch threads only talked about when posts would be made, which is different from the rewatch being a community event that people show up for and discuss at the same time, e.g. what Galactic Watercooler (and other Frak Parties) used to do on their forums.
All of which is to say, returning to essence of my original post, that I agree with TwitchSurgeon that the rewatch threads don't have a value-add as they exist right now.
