One more thing about Member Profiles:
If you're viewing your own profile, the listing of books will show any bookmarks you've applied, and they're clickable (taking you to your Bookshelf, with just the books with that bookmark displayed).
If someone else clicks on your name to view your profile, the list of books won't display your bookmarks. Likewise when you click on someone else's name, the books listed in their member profile won't show their bookmarks. But if you have books in common, the listing will display your bookmarks, clickable with the same behavior as described above.
