Moving profiles to Wikifudia

To make user profiles a bit more relevant, I'm planning to move them to the User: namespace on Wikifudia and port over any info as wikitext.

I've put together some brief templates to let you see recent topics by a user and any social network links they may have entered, as with current profiles.

Things like instruments can go is as normal wiki links, then you can find a trumpet player by searching all the User: pages that link to 'trumpet'. It'd be nice to keep the instrument family groupings on the current musician finder though - any suggestions as to how that could work in wiki form would be welcome - maybe just a category on the instrument pages?

I need to test a plugin to restrict viewing profiles to logged in users only - or do you think that is even necessary?
