I have a question concerning the User Control Panel, more precisely the 'manage subscriptions' and affiliated options.
I can see there to which threads I'm subscribed. It are threads I've been actively posting to and have at one point marked the 'subscription' option while making a post. But is there a way to subscribe to threads one isn't posting to (and never will post to)?
I have a few threads - in the Scriptorium and the Pony - which I read, but it is in the nature of those threads that only those writing the stories post in them (and can subscribe by marking that checkbox). There was a time when checking up on those threads on an almost daily base always resulted in finding new posts being added, but the frantic writing of the days of yore seems behind most - it would be nice to be notified when a post was made, though.
I thought that now that we have the 'manage subscriptions', there might be an possibility there to enter the url of a thread manually, but apparently it doesn't work that way.
If I'm overlooking an obvious solution to which I would like to achieve, please enlighten me.

Also, how do the manage bookmarks, draft etc, work? Or are they not active yet?
(I am sorry if any of my questions have already been asked before)
