AMAZING work on the new site, it looks great and intuitive, and I can't wait to settle in! I do have a weeny problem already though, and it's probably my own fault for having silly HTML on my profile in the first place... ;)
I'm on Mac OS X 10.5.8, Firefox 3.6.3.
When I try to update my profile blurb, (http://bookcrossing.com/editprofile/Lottiotta) I edit everything and click "save". Then I'm taken to a log in page (even though I'm logged in), I get to this URL: http://bookcrossing.com/---/LogIn?... Which looks like this:
When I put in my email address and password correctly, I get back to my bookshelf as I should, but my extended profile has not been saved.
Hope this helps! :) I have my bookshelf code saved so no worries there.
All the best!
