I just figured out what those little suitcases on the left are for.
Hehe. Those are supposed to be envelopes and I, too, wish they'd change color.
As for the font issues that several folks mentioned, I tried a couple of fixes that didn't seem to work (they did nothing for me, anyway) but I do know that the vBulletin team is aware of that issue.
I also know they have several "planned" updates scheduled out over January and February. They didn't consider editor fonts a critical bug (no surprise) but I suspect it'll sneak its way into the updates.
I will, of course, keep the forums current and hopefully these annoyances will drop off over time.
