KTCAOP sent me. How can I help?
Shoot me a Private Forum message with your preferred email address for Waze related communications and I’ll invite you into the Nebraska Google Hangout. We use that as the primary communications platform for Nebraska and other Plains states.
Welcome Hamhouke! I know you’ll enjoy map editing. Hope to see you in WME! 
Glad we got to chat in Google Hangouts! There is always something to do and fix in Waze and we look forward to working with you.
Some quick places that are worth their own bookmarks:

See you on the map!
