Marking posts – SOLVED

Hi there,
I go through the forums pretty regularly, searching for solutions as well as trying to help out where possible. Is it possible to give the users an option to mark the post as SOLVED. This eliminates the need to read the post if trying to offer help but also allows me to jump to the end and find a solution if its a long thread.

Special thanks to user: yasse for marking his completed post as solved. First time I ran across this. So hoping something can be added to the post that allows the post to be searched / filtered by solved

Thanks
