Virtually the only thing that would really please me to see here, would be expanded publicly viewable personal bio page - the same as you have on all other internet fora. Where when you simply click on a members name, and it pulls up a page which contains - as much or as little further info - on them as they choose to offer.

Including of course (as this is a music site) links to their favourite and/or Own music sites...!

It would make understanding where someone's comments are coming from when they post, so much easier, as there's some context.
