A wiki is a website that allows visitors to add, remove, edit and change content, typically without the need for registration. Palmpedia does require registration in order to utilize this ability. Registration takes seconds. Just click on "create account." Palmpedia utilizes the same efficient software that runs Wikipedia.
A wiki also allows for linking among any number of pages. This ease of interaction and operation makes a wiki the most effective tool for mass collaborative authoring. The term wiki can also refer to the collaborative software itself (wiki engine) that facilitates the operation of such a site, or to specific wiki sites, including the computer science site WikiWikiWeb (the original wiki) and online encyclopedias such as Wikipedia.
