What the fuck are they?
I have one for Vista (I use Linux, so what the fuck?), Firefox, and a UK flag. And two that just link to the FP home page. So what are they there for?
They're links to the FP home page.
The one next to the flag is supposed to be your event history. (bans, thread locks, moves, renames, etc.) The button on the far right is supposed to be the report button, dropping down a list of report reasons.
Apparently something on your end is broken if it's just returning you to the home page.
Also the OS icon just shows what OS you're running under (though if you're running something in wine for some reason it'll show as Windows) and the browser icon shows what browser you used to post that post with.
Flag, obvious. Shows what country you posted from.
No clue about the vista thing but the links which are a book and calender are your event log and report buttons. If those do not work properly your browser has a problem.
Ah, okay. They're working now for some reason.
Are you on drugs, dude? It obviously shows your OS, browser and country you live in.
