Mark a Topic as Solved, for myself

[PGStats]

I would like to be able to mark a reply as a correct solution, as far as I am concerned, even if the OP hasn't marked it as such. The topic would thereafter appear to me as solved in every topic list. 

Such a feature could eventually allow for topics to be labelled as resolved to the whole community if a significant number of members signaled it should be.

Or possibly just an "ignore this thread"?
