I've spent the better part of the last two weeks adding speed limit information using Potlatch 2 to my local area (Alexandria and Pineville, Louisiana, USA). Still waiting for the data to begin showing up in Skobbler, about how long does it take to update from the OpenStreetmap data?

Also, what exactly are the sign posts? Are they visual representations of the speed limit information? Exit numbers with the towns they exit to? I'd certainly like to add these to my local area as well, just need feedback as to what goes where.

Love the product! Skobbler is the first app to make OpenStreetmap really practical and useful! It's encouraged me to do a lot of work in my area, and I'm happy to say that it's now at least as accurate as the Google Maps, if not more so, because Google Maps is missing several new residential subdivisions.
