To 01,27,2023 I'm pretty new here too, but it's a website set up by a particular artist. Some of their work is hosted here, and there's a number of ways to chat. Some membership features are invite-only, though. Each user gets one invite. I was invited by a friend of mine, and I don't know who invited them. There's a sort of vaguely mysterious atmosphere around posting here, but it's ultimately a web forum of a kind. I have some hunch some interesting changes to the site might be made sometime soon, though.
