I am considering using a Wiki as the framework for a project that will involve a group of widely dispersed individuals. I want to set it up first on my home network to work out kinks, and then host it elsewhere when the collaboration starts. I'm considering using MediaWiki as the platform for this. I have apache running on a Mac Mini already (running Mavericks), and will use that as my local test host. Any suggestions on (a) MediaWiki as the platform, (b) getting MediaWiki running on a Mac , and (c) a good final host for the wiki? I want to go with open source rather than commercial for the platform.
