[Forum feature] mark participated threads

Every time I’m browsing the forums I’m having an hard time to understand what threads I’ve commented on, and which ones I haven’t, ending up wasting time to go to my user profile and see my activity.

I’ve seen this implemented in different ways, one is the suggestion I made, i.e. having a way to visually identify the threads, another one is to have a link at the top of the forums that brings you to the list of threads participated.

Not a biggie, just something that might improve participation.
