Image tagging changes (custom tags!)

Model tags and tag subscriptions are both pretty high priority, more so than negative tag search.

I've discussed why I'm not renaming the "teen" tag to "young" on the forums before, but it boils down to: First, "teen" does not imply minor as 18 and 19 are numbers that exist, and second, "young" would get misused even more than "teen" does currently on basically anyone under 40.

I assume nationalities such as greek, brazilian, etc. would be considered a model tag?

Yes.
