[[Couchwiki.org]] is an independent wiki with information for people who are actively exchanging hospitality.
Guaka is Kasper Souren. I'm a CouchSurfing member since Summer 2005. I used Hospitality Club before that, and I'm a fan of BeWelcome since its inception in 2007.
I joined the CouchSurfing Collective in August 2006, started the CouchSurfing wiki. He was CouchSurfing tech team coordinator and global ambassador until early 2007.
He's a Wikimaniac and administrator and sometimes even (co)founder of many other wikis (such as the Hitchwiki and the Bambara Wikipedia). He has hitchhiked on 6 continents.
He speaks a bunch of languages and defines himself as a social geek.
