This forum is probably the best place to find that kind of info. The general plan, until something changes, is to hold two month-long jams every year:
I will also mention upcoming jams in Decker release notes.
I'm open to other methods of handling announcements if folks have suggestions!
I wonder if a persistent pinned post in these forums would help, as sort of a master list of previous jams as well as when the next one is scheduled. Once a jam is over it can be a bit hard to track down the link, I've found (unless I am missing something, which is entirely possible), so this could help newcomers be aware that there's jams on a regular schedule and also showcase the previous jams a bit.
