I just recently was to an area where there were lots of Waze users and now I have questions:

1. I saw some Waze icons on my screen on the Waze map that looked like they carried a sword, had different colored hats on and some Waze icons were even different colors. What do the colors mean and how does one acquire a hat or sword?

2. I had some Wazers Ping me, but I couldn't respond because I was driving. Can I voice a response to them and it will show up as text to them?

3. One Wazer thanked me for letting them know there was a cop at a certain location, how did they know it came from me?

4. When my friends use Waze and go somewhere, I get a text from them (probably forwarded to my phone from Twitter or some other social network) similar to this: "Driving to (location), sharing real-time road info with Wazers in my area. ETA (time) using @waze - Drive Social!" How can I send my info out to others? What are the steps I must take or do to make this happen? Do I have to type all of that or is it automatic?

Thank you for your assistance.

DALE.
