I'm Edward Kaye (no relation I assume). I have been voting and moderating on MusicBrainz for some time now, but I have only just started using the wiki, in order to suggest new ARs etc.
I currently have a proposed advanced relationship for a supporting musician catagory, which is designed to replace band member info for solo artists, please check it out: SupportingMusicianRelationshipType
Also, please vote on my moderations, I don't have many up at the moment, as I just started a new job and don't really have much time at the moment: http://musicbrainz.org/user/view.html?modname=edkaye
See you around,
