Welcome back! In general things haven't changed that much. It's still a bunch of people spending way too much time thinking about and talking about slinging.
There's a lot of current forum activity from some newer members, which is great! There's some really good sling makers who have joined this year. And one member (rasul) who has established a successful slinging club in California.
We also have two new boards on the forum. Sling Academy, which is dedicated to how-to videos, demonstrations, and things like that:
https://slinging.org/forum/YaBB.pl?board=SlingAcademy. And Catch This, which used to be a board dedicated to a sling podcast, but now has been opened up to all social media content related to slinging:
https://slinging.org/forum/YaBB.pl?board=Podcast. The social media board (under the new concept) is still pretty new so there's not much there yet.
