Strange but true: only in the last month have I realized that for most people, little pictures appear next to users' names in their posts!
That was on a Linux/Konquerer system. I use Windows/IE everywhere else, and in none of those (IE) browsers do I see the pictures next to users' names.
Not a huge thing (well, a revelation for me!), but thought you'd want to know, maybe see if anyone else has that happen.
