Greg, I've noticed that a lot of us like to refer back to older threads every now and then and have to bookmark them in our browsers to avoid having to search for it every time. Unless one uses a service like Delicious or Xmarks, these bookmarks remain specific to the browser and computer. I've noticed in passing in other forums that they have a "sticky" feature where a user can pin a thread to the top of the threads list visible only to that user when they log in. Or perhaps something that will allow a user to "save" a thread to their "favourites".

This is just one of those nice-to-have-within-YLF features that I think will help everyone as the forum continues to grow at the rate that it is!

Thanks for all your hard work!
