Hello everyone, I really hate to write this because I know it will cause angst for you. We had to change our profile and bookmark system and it probably lost your previous bookmarks. I am sorry for the aggravation. The other one was no longer working correctly. It controlled the user signups here and it was allowing a lot of spam users to register.
One you start using the new bookmark system, you will be able to find your bookmarks by hovering over the profile link in the main navigation menu.
Again, so sorry for the trouble.. I appreciate your patience.
