Mac users have their own Wiki at Wikitosh.

Wiki's are a selection of Web pages that are editable by site visitors. Wikitosh is a Mac community Wiki that aims to discuss "all things related to Apple and Macintosh", site webmaster Jack Arends explained.

A variety of reources are available - including tips for beginners and professionals. The site is freely expandable to cover any new subjects that may be of interest to the Mac Community.

"Since the content of a Wiki is entirely user contributed there may of course occasionally be errors but Wiki's tend to be self-correcting as later readers can correct or clarify previous entries," Arends added.

Wiki's are emerging as a third part of the Internet-based community resurgence, heralded by the emergence of Podcasts and digital music clubs such as Playlist.
