I think that Wed sounds good this week so that we can all get in on

I would welcome a more casual get together on Sunday as well, to poke
at the embers of Sensebridge and generally check in.

Kristin, Thursday nights are occasionally lost to 5mof, but we could
potentially take that risk if that's a good day for everyone.
