GUYS Solo lost in ladder game FFA02
Such message contains link to player (Solo in this case) but doesn't contain link to the game. Sometimes I'm interested to watch what game this is but there are troubles to find it, because I should know who else play this game to visit their account page and see the game.
Would be good to supply such messages both links to the player and to the game.
