Hey, sorry for not getting back sooner. I made a change to how jams you've joined is displayed. They will no longer take up place on the jams page after they've ended. This should prevent old jams you didn't get a chance to participate in from cluttering things up.
Viewing post in Remove previous game jams attended.
That change is nice enough, but now there's no way to view past jams we've submitted a game to at all...
A couple of days ago I requested this instead: https://github.com/itchio/itch.io/issues/867
But maybe jams we've participated in could get its own section on top of https://itch.io/jams/past, just like how jams we're currently enrolled in are displayed separately on top of https://itch.io/jams? Would that be a nice compromise?
Edit: I just found out that I can see jams I've submitted games to in the dashboard: https://itch.io/dashboard/jams – Since I don't care about jams I've joined but not submitted to, this is enough for me!
