Like about 5000+ of them. They all got poofed away, to quote Homestar Runner. I also cannot upload any. I have been meaning to sort that whole folder out, but this seems a bit drastic a solution.
I dunno if this a server issue or what, or if there's anyone else experiencing this issue, but it's throwing a spanner into the works with much of the antics I get up to around here.
