Mark Solved on these forums?

I’ve seen before on other programming forums where they had an option to mark a topic as solved so nobody wasted time attempting to solve a solved issue. It this possible with this specific forum software? Not sure if it is possible but would be a handy feature. what do you guys think?

Something like this: http://custom.simplemachines.org/mods/index.php?mod=1601 or this: http://custom.simplemachines.org/mods/index.php?mod=7

I think it would be great to have something like one of these installed to mark if something is solved/unsolved.

I think we just EDIT our original post and add [SOLVED] in front of the title...
not elegant, but it works fine...
