I don't know if this exists but I didn't see anything about rating individual users. I think this feature should be added especially for game jams where it's about collaboration and team building/trust.
I recently joined a game jam and built a team all on this website. We started off strong but then in the last week, I noticed things have gone silent where only one person was responding slowly. Ultimately, both my team mates abandoned the project completely last minute. I've tried messaging both asking what's been going on but all I've got was radio silence.
It sucks because I had to forfeit the jam. I'm not a generalist and now all the work I've done goes down the drain because two people decided to be not great team members.
I think it's important that we can rate other users based on their people skills. It can be a simple star system like the games or something. This also saves other people time and have a sense of security especially if they aren't blessed with friends who can help create a game. Frankly, it makes me really wary about this community if I wanted to join a team here again.
