http://www.simplemachines.org/community/index.php?topic=17178.15I have no idea how easy it would be to implement, nor can I vouch for the stability of above mod. That being said, a "Bookmark Thread" mod is something I have dreamed of using on this forum since I first joined, over 3 years ago.
Having bookmarks at the site level (ie: profile) would allow users to follow their favorite topics from any computer.
Just a suggestion...
