It's just more of a button that you click on and marks all forum boards/threads read from my perspective.

From looking at the updated forum, the exclamation point (green) means that I haven't read that forum thread yet.

Oh, now I see what you mean.

Yeah, the green ! means that there are posts you haven't read yet. I don't think something like that exists on the forum at this moment, though with threads (primarily those that are roleplay threads) being updated/posted in rather frequently, I imagine something like that would be of a lower priority than most requested features.
