Are There Any Other Dreamcast-friendly Forum Sites Around?

I recently got my Dreamcast online and just made this account. I was kinda wondering if there are other forum sites around that the Dreamcast/older computers in general can access? For example I'm into anime/retro anime; is there somewhere I can talk about that stuff on my Dreamcast?

I've been online for a little bit and it's a bit difficult honestly.
Realistically, any site that can be accessed with http (not HTTPS) should work on Dreamcast.

There's a retro search engine called FrogFind that's fairly useful, but you're going to get a lot of archived sites.
Unfortunately it's pretty challenging to find sites now. Most sites are HTTPS which no Dreamcast browser (that I'm aware of) supports.

Definitely going to be keeping an eye on this topic for any suggestions.

---------- Some say its still thinking, even all these years later.
