There are lots of icons on the pages, and I can't find a legend for many of them! Some I could figure out, and it took me a while to realize I could mouseover many of the others to get info, but there are still some I'm not completely sure about (e.g. purple closed envelope). It also took me a bit to figure out what the bold vs non-bold links meant; I originally thought it was non-bold if I had the last post in it! It would be nice to have a nice little page on all of these little details that make forum surfing more convenient; I didn't find anything obvious in the FAQ table of contents.
