Does this link launch Fistful of Frags? If not, re-installing the steam client should resolve the issue. You can also manually connect to a server address through the game console (enable in settings then press ~), or by adding the server address to your favorites list in the server browser.
You will be automatically connected to the server.
All player actions are logged and the performance of each player is tracked. You can see those stats here: Fistful of Frags Stats
While in game you earn uLithiums for every kill you get, a detailed break down can be found here: Fistful of Frags Information.
