I'm sure this is old news for you now, but they were having issues for a couple of days. I lost posts, comments and some design changes too. It was annoying.
It's all what Magaly said! It happened last week, I think thursday to friday! Fun stuff! But, I think it's all better now ;o)
not really better... some of my comments never came back. oh well.
Thank you for your comment! :)
