When I click on the players list for tactics trainer, the list looks incomplete. The highest-rated list starts at 2664, but the last time I checked there were people in the 2700/2800/2900 range (and one person at 4000). I also searched for certain members that I know use tactics trainer, but their names don't show up. Looks like the list is incomplete.

I believe the reason for this is that the Tactics Trainer player list only shows "active" Tacticians who regularly access the Tactics Trainer.

How active? I've been using TT virtually every day in the last few months. But I only do 3 problems a day, so maybe that's why.

Actually, somebody asked this question in another thread. I see it was just an error. Although there still seem to be some people missing. Cuendillar comes to mind immediately.

Tactics trainer is good but to learn tactics chess mentor is much better which i reccomend. CHess mentor has more difficult complex tactics while tactics trainer to me seems like a prep problem before tournament games.

Also tactics trainer rating is false. I am not saying that because I have a low tactics rating but high tactics knowledge I actually use in a game but tactics trainer has one problem rated 1400 which is much harder to complete than the 2100 problem. Also tactics trainer uses the same problem rated 1500 as 1800 same exact problem but a much different rating if u complete it.
