If you haven't voted already, there's no time to waste! Well, actually there's two more weeks, but last year it lasted for a month as far as I remember.
Half-Life 2 and Battlefield 2 currently lead, according to the chart... with Half-Life on the first place.
By the way, it's most probable that unregistered votes won't be counted at all. They will be taken into account only if there's a tie in registered members' vote.
So, if you still haven't registered, I suggest to do so.
One more addition... seems that someone's trying to reduce the mod rating. According to "Community Rating" status on ModDB, our rating is 8,1 out of 10 now, and it was 8,6 only a few days ago. This is possible only if several people submitted poor ratings (1-2 out of 10) in a row, which can hardly be a coincidence.
There's only one way to deal with that - submit better ratings, and collect more positive votes. So, if you are registered, you can go to the profile page, find Community Rating, and submit a vote...
