Sorry to slightly drag your thread off-course, but how does this work in the first place?
I have managed to tweet reports onto my group twitter feeds from members, but I've never seen what looks like a twitter tweet displayed on the Waze client. Some of my group members have asked for this as I retweet information for another traffic source to users too.
