I have clicked on subscribe to certain topics but yet to see what it does (maybe I am missing something?) but either way my suggestion is for our forum profile to have an option “View subscribed threads” so I can have these topics in one handy area instead of searching all my forum posts or checking the forum areas i visit often to see if there has been a reply yet.
I would also suggest along the same line that any topics we create ourselves are automatically subscribed to – it would make sense
