A suggestion

[Paul M]

The lack of a site link has always annoyed me as well Adrian, combined with the fact that half the urls are invalid as well (that's a bit of a bug really). I don't think it's privacy in most cases, because if you ask, most people post a link. I think it's just the fact that people don't update their profile, so I don't think such a tag would really help in the majority of cases.
