Sup everyone, I got L4D for a little while now since it came out. I beaten all the campaign and expert and now i'm just always playing versus mode. Hoping new levels will come out but until then i'm looking for a group of people who just wants to play together at least. with a bit more than randomness with public games i join. I play usually after work and at night, I'm from Los Angeles, CA so lets have some fun, i'm semi new to the steam thing even tho my account is super old and my account name is based off my OLD OLD OLD email. so is there a way to add people by groups or join a group of friends or do i need to add each and everyone? also can i change my steam id ?
