Join the discord is a great way to get connected, and then you can subscribe to the announcement channels keeping track of future jams. There's also another jam overlapping in there about finishing old unfinished NSFW jam games ^^
I meant itch.io itself. I might join Discord (when I have a phone nearby), but for now I'm interested in exactly how it's done in itch.io.
Actually, I didn't notice they had a Discord, so thank you.
