Here’s one more for that list – quite an obvious one, but I did not get on this idea. Somebody else from our forum did.
- tags on “personal” topics
Personal topics would be just a convention: one topic per user, in a certain category. That way, these topics are proxies for users. The category for them can be public (so users would publish their personal topics themselves) or not (so staff members can internally store information about job applicants, for example). The available tags can be bound to that category (e.g. using a “skills” tag group) so that they cannot be used on “normal” topics.
