I was thinking, maybe we could have different username colors. For example:

User: Orange
Premium User: Red
Moderator: Green
Writer: Yellow

Or something like that c: And their username would show up in that color in the forums and on their profile.

This isn't really an important suggestion, though, just something I thought would be pretty cool.

I think showing ID numbers next to usernames would be nice. The site is growing and there are a lot of people with similar names. I know usernames are unique- but it really would help to distinguish users more (especially for people who may be a bit dyslexic).

This would be nice. :)
Even just a different color (sticking with the pale palette) around the avatar box would ne nice.
