Here are the top twenty episodes for TNG according to your voting over the past month or so. I am certain this list doesn’t match your list of top twenty; it most certainly doesn’t match my list. But here it is as the forum voted (Star Trek democracy in action). Feel free to discuss and let everyone know how your list of top twenty episodes is better. Nicely, of course. 
The list is in order of how the voting turns out in each round, placing the winners in that round on top. Not necessarily which episode got the most votes over all. All Good Things was kicking butt all the way through the voting until the final round, which it came in last out of three episodes. Go figure.
