I would like to play a game in messenger plus with a friend. The menu actions is not showing this option. What am I doing wrong. I also thought that when plus is installed you should see this as a sort of wings behind teh messenger icon in the left low corner. Also not availlable

The question is why am I not able to play online games?

For the games not showing in actions i'd say reinstall MSN messenger.

For the wings not showing: could u be more specific wich wing in wich screen?
Is plus in the menu in ur main messengerscreen?
Do u use any skin?
