Is there any sort of bookmark feature?
 

Periodically there are threads that have information I'd like to mark for future reference, or that I can't look at closely at the moment but want to take some time in the future. However, sometimes I forget what thread it is.

Is there any way to mark threads or posts so we can easily find them in the future? Like the Favorites feature on CB.

I think subscribing to the thread might do what you're looking for.
