This is where we do what we do! We talk about playing table-top role-playing games.
This is not a play-at or streaming site - it's for discussion of what you're already doing. People often include video or audio recordings, but text-only is fine too. You can also attach documents, like maps or character sheets or brief sections of the rules you're using.
I trust you to work out how you want to talk about your games. If you'd like, check out my best-practices manual for suggestions, but it's really flexible.
If you already do a podcast or other actual-play series, live or not, please consider yourself invited to embed a link as a topic.
For games in design, i.e., playtesting - yes, go right ahead, that's welcome too. For consulting sessions with me, which is different, see the Consulting page.
