After struggling to build my own signature (see the oh-so-elaborate one below), I thought I would get people started with a few helpful links that would have cut my time of building my custom signature down to about 5 minutes (instead of 30 minutes).

General Signature Rank Badges/Icons/Shields:
http://sign.waze.tools/home/

Click on the "HowTo (guidelines)" tab on the far right of the tabs for a detailed step-by-step on how to include the badges in your profile as well as an explanation of the Waze Community's recommended sequence of badges and icons.

Those of you out there that have other tricks and tips, please do reply with them!
