I'm sitting here with my kid watching "Barney". They're singing "Mr Knickerbocker", and watching that Hammer avatar jam in synch is kinda freakin me out.
But back on topic..... I used my filter for the first time last night.

I only entered 20 into the players slot. Like 150 servers listed in just a couple seconds. Then I clicked ping, and went to the besy available Coral Sea, which is my usual start off. After a few rounds, I did the same for Omaha. If the Omaha server doesn't change maps after a few, then I look for El Alemein or something "high player/low ping."
