Hello, Tim! Welcome to Wikitravel. Please take a sec to look at our copyleft and policies and guidelines, but feel free to plunge forward and edit some pages. Scanning the Manual of style, especially the article templates, can give you a good idea of how we like articles formatted. If you need help, check out Wikitravel:Help, and if you need some info not on there, post a message in the travellers' pub.
Thanks Evan. I'm an old Wikipedian who just discovered your site. I think it's a great idea and off to an excellent start. - Tim
