*Great Loop* - The boat circumnavigation of Eastern North America by water is known as *The Great Loop (*http://en.wikipedia.org/wiki/Great_Loop) *WiKi *- A community collaboration website that allows the creation and editing of any number of interlinked web pages (the database) via a web browser. (http://en.wikipedia.org/wiki/Wiki) The four basic types of users who participate in wikis are reader, author, wiki administrator and web administrator. I'd suggest only Great Loop members are granted author rights on the WiKi to post and edit content but the public is given reader rights to view all pages but not post or edit any content. Which WiKi software to use and who to host it? See http://www.wikimatrix.org/ Enjoy, Douglas Pohl GREY GOOSE outfitting in Mobile Alabama for a return home voyage in 2012 to Astoria OR
