Don't forget to order your supplies for this year's International BookCrossing Day (April 21)! The last day to order them is March 25, because we'll need time to get them to you before the big day arrives. And this year's labels were designed by Azuki and they're great. So don't miss out, get your orders in while you can!
When you say "posting thank yous", do you mean posting a reply in the forums, or sending a Private Message to the specific person? And are the problems in the form of error messages from the site, or are you having trouble finding the right forum thread or BCer bookshelf in the first place? [If you're getting error messages from the site, try again a little later. And if you're trying to post in the forums, an error message may not mean that your post didn't go through, so look for it before trying to post again.]
