PBworks (formerly PBwiki) is a commercial real-time collaborative editing (RTCE) system created by David Weekly, with Ramit Sethi and Nathan Schmidt joining shortly thereafter as co-founders. Based in San Mateo, California, the company's original name stems from their belief that "making a wiki is as easy as making a peanut butter sandwich". The company operates on a freemium basis, with basic features being offered for free and more advanced features for a fee.
Wikia is a collaborative publishing platform that enables communities to discover, create and share content on any topic in any language.
Wikia sites are written by community members that are passionate about subjects ranging from video games, TV shows and movies to food, fashion, and environmental sustainability.
Some of the biggest communities on Wikia are in gaming and entertainment, such as World of Warcraft and the Marvel Database Project, but comprehensive sites on genealogy, ice hockey, and children's books keep a diverse number of people interested and engaged. There’s even a wiki on solar cooking!
What's the name all about? “Wikia” is derived from the Hawaiian word “wiki” - which means “quick.”
MediaWiki is a free software wiki package written in PHP, originally for use on Wikipedia. It is now used by several other projects of the non-profit Wikimedia Foundation and by many other wikis, including this website, the home of MediaWiki.
