Is there a way to mark a thread one wishes to return to, short of subscribing? By subscribing, we only get notices if there are new posts, but there are threads I would like to pursue more thoroughly when I have more time whether there are new posts or not. If I could mark, or flag, them somehow, they'd be much easier to find again. Is this even possible?

Thanks!

In the userCP/Edit folders, you can organize favourite threads in a way similar to bookmarks. Just subscribe to those threads, and choose "No email notification".

Thanks Wa'il, I'll give that a try!
