Valve/Steam Scam
Phishing Scam: http://valvegame.t35.com/
PLEASE BE AWARE. There is a currently a steam message doing the rounds using the above url in the message body that is not related to Steam in any way.
It looks very authetuc but it's not. The page ultimately requires you to login but you are NOT signing into steam. You are giving away your details to your steam account to some unscruplous nut sack.
If you are using Firefox then please make sure that you see "Valve Corporation" in green on the right hand side of the web address and that the web address is http://steamcommunity.com to make sure you are on the correct site.
Sadly IE is not so good at showing you this but please be prudent and vigilent.
If in doubt please use Steam to access it's Community and Shop.
