Mumble is a great form of communication between players. Use it in conjuntion with VOIP and your all set. Mumble works like VOIP does, except it's positional audio. You hear what your player hears. Mumble is like giving your player a voice in game, instead of being a voice on the radio. People near you can hear you.

Here's some instructions on how to set it up, and some helpful hints:

I also highly HIGHLY suggest you read the manual. I also suggest you read tutorials on the game as well, such as grenadier,LAT,HAT, etc. I also recommend you watch THIS tutorial on Deviation and Marksmanship:
YouTube - Project Reality: Marksmanship and Deviation Tutorial
It explains many things, it has up to date information.
I also recommend not being a squad leader for the first few games you play. Instead, play as infantry, and watch what others do, and do what they do. "hardcore" servers are the best ones to play on, since they have the most experienced players, and usually staffed with admins. Most of them are willing to help as well
PR was designed for the serious, mature gamer in mind. Consiter this when playing with other people. Kindness and courtesy go a long way.
When you first start playing PR, play as a simple rifleman. Do what your squad leader says, and keep an open mind. Always be careful, and ready for anything. Always have a plan.
Besides that, stop by a training server and play a few rounds there. familiarize yourself with vehicles, weapons, etc. It's always good to learn new things, making the game more enjoyable.
