I had that happen once. I closed blogger down and when I re-opened it, they were back.
Same as amandakiska. First I almost had a heart attack, but then closed and reopened. Thank goodness everybody was back. I was so scared.
Ooh! Not good. Haven't had it happen, but I hope they turn up again soon! Rereading your last post, I feel the same way. I am still wearing the same clothes and have realized that I must have been wearing them WAY too tight and they must have looked crap! Here's to new pants in the near future!
