For those of us that keep trying a Tactics Trainer problem until we get it right, I suggest not displaying the "Suggest Tags" or the "Vote for a tag" until you solve the puzzle.  To see the Suggested Tag(s) gives a hint that I don't want until I solve the puzzle myself and you shouldn't be permitted to suggest a tag if you haven't solved the puzzle (or seen the solution by clicking "Show Solution").

Knowing Chess.com, this suggestion has already been made a few hundred times and the programmers are working on it but I haven't seen this idea on the forum so I thought I would throw it out there.
