i am in Johnston, Iowa and every time i just to update or edit it won't let me save

editing is working now...thanks

also do you earn points per edit or how is that scored?

Start editing!

Also for every 500 edits, you get a bonus candy worth 750 points on your next drive. When everything is added up, 500 edits equals 1500 points. Happy editing, and please don't complete edits unless they are correct. It's sad to see so many edits in my area that are poor, meaning the map in my area is poor and leads to bad routing.

yes you do earn points for editing. check in the Wiki pages it show the points earned for everything. I forget what you get per edit right now, otherwise I would tell you.

i saw them after i posted, i didnt realize there was a second page
