Yup. I also noticed it earlier on one of Bear Nenno’s posts. I’ve also noticed that there are other messaging options listed in the same place on some people’s posts. I’d hazard a guess that it would only be active on Members’ accounts, since “Guests” don’t have things like location and post counts listed. It seems like a similar thing.
I don’t see it on your post, aruvqan, but there is a little flower with one red petal (MSN? I remember this vaguely from long ago). There have to be settings in our profiles: I’m on Skype and AIM, but they don’t show in my posts.
In Skype, under Options >> Privacy, disable ‘Allow my online status to be shown on the web’, ‘Accept Skype browser cookies’, and ‘Allow Microsoft targeted ads, including use of Skype profile age and gender’. I don’t know which one(s) make the Skype links go away, but I don’t want any of them.
