I pretty much agree with everyone else. Just remember the "5 W's" of making a position report. 1. Who you're talking to 2. who you are 3. where you are 4. what you want or want to do 5. who you're talking to (if no tower or ATC is present)

One thing that has been shunned from the AIM is requesting "Any traffic please advise." This is to help cut down on any unnecessary radio chatter, which is one of my biggest pet peeves coincidently. Usually if I am hearing a lot of chatter on the frequency, I usually very quickly and briefly ask to "cut the chatter" because it is annoying and may prevent someone from making a necessary radio call.

The FCC frequencies designated for air to air comms that can be found in the AIM 4-1-11 Table 4-1-3.
