There was a time where I was part of around 5- forums each for specific media, I even owned a couple.
The last one was a local marvel forum owned by two friends, we had a small community and held get togethers and hang out, I loved it but they didn't want to host it anymore or manage it and switched to a facebook group, discord wasn't that popular back then. Once in a while I hop on to that group to see what's up and see if there's some event planned but I can't stand facebook or the groups. It's a lot of posting memes and macro images now instead of actual discussion. A shame.
Luckily resetera has everything in one place.
