@Dwenaus – I think my statement was quite capable of being misunderstood.

What I actually meant to say was:

It would be a good idea to extend this plugin in such a way that users would be treated the same way the groups currently are.

Users could assign tags to themselves (e.g. Wildrot: brown-haired, brown-eyed, non-programmer) and the user directory could be searched via these tags.
