I'm new to this site so I'm not sure if this was ever a working feature, but I figured I'd submit it anyway. If it's never worked this way, perhaps it could be a feature enhancement to the site.
A GeekBuddy of mine added me as a player in one of his game play logs. Intuitively, I assumed that play would also show up in my profile, but it didn't. I had to add the play manually in my own game play log. Is this something that's been broken by updates or has it never automatically updated your profile when another user "tags" you in a game play?
It's been discussed. Consensus is that we don't want people to be able to 'tag' us against our knowledge and/or will.
