I just added 500K, 600K, and 700K banners to http://www.waze.com/wiki/index.php/Forum_Signature_Banners
Is anyone currently higher than 700K that wants a banner for their number? I can keep going.
I think it is best to convert to "1.xM" after "900K". That will be pretty easy to do and keep the current banner/shield layout. I will save the Photoshop template so I can create any number possible. If we want, I can upload the layered PSD file somewhere into the Waze community so anyone can edit it if I am no longer here sometime in the future.
