Nice work, looks quite consistent 
If you’re working on the color scheme, it would be great to make a few general tweaks.
- Lower the contrast of non-important elements. Link colors in footers shouldn’t be radioactively blue. It stands out, make short posts more difficult to read.
- I’d make all those titles like “Visionary” and “Champion” greyed out. I don’t need this information at all, it’s weird and childish. But some people like it - could we just remove bright colors so the thread won’t look like a christmas tree?
Change #2 would make #3 easier to achieve.
3) And Epic members should be marked by special color (maybe by special background color/shadow of the “post author” section?), not this tiny and ugly badge. This way we would quickly notice this quite important information.
Once again, look at GOG forums. It’s super clean and easy to read. Could we get a bit closer to such usability, please?

While you’re making changes, maybe you could remove member’s “join date”?
