Often in Tactics Trainer, there is a really relevant tag missing from a problem. It would be very simple to implement a system where anyone can submit a tag, but also anyone can vote up or down on a submitted tag, so false/inaccurate ones disappear. Let users do the work for you!

I'm not a programmer, are you? Just wondering how you know that it would be "very simple" to implement anything around here. I've used the TT for several hrs and quite frankly don't see any point to your suggestion, there are plenty of options and features available as it is.

How does anyone voting on tags equate to some sort of a qualified or authoritative opinion or rating anyway?

Works great on chesstempo.
