Explanation of Forum icons
 

Could someone explain the icons? At least the open/closed envelopes make more sense that the concentric squares from 3.0, but:

when i respond on a thread, why does the icon become a *closed* envelope with a black dot (the black dot, i assume, means that I have a post on the thread).

what's the difference between a red and yellow envelope?

why do some envelopes stay closed when I've already read them? why are some envelopes open when I've never touched them?

what else am i missing in all this?

look at the bottom of the forum page for explanation

right now we are using the default icons for the bulletin board software. I haven't had time to create new ones yet.

oo, i didnt even realize about the black dot on the envelope. thats cool :)
