Mapper since: December 30, 2006
Author of the book OpenStreetMap from Packt Publishing. Please use the Packt web site to report any mistakes you find in the book — I can't deal with them directly. I also can't respond to individual queries, but am happy to answer questions via the OpenStreetMap Q&A system, where other experienced mappers are also available to help.
Mapping Guildford, parts of Scotland and the odd bit of Nottinghamshire.
Happy to be contacted over any mapping I've done -- just use the messaging system. I can also sometimes be found on #OSM as JonathanB.
Twitters as @jonobennett. Also on Google+.
