Among MediaWiki developers, there has been some discussion about which extensions should be bundled with the MediaWiki tarball. But, up till now, no one has really done anything about it.
In order to get the ball rolling, I posted a request for an idea of extensions that people would like to see bundled with MediaWiki. There is even the possibility of (eventually) different bundling options or a “MediaWiki lite” that has just the bare bones.
Chime in and let us know how you think this should look.
The math (latex) plugin and the sourcecode highlighting plugin!
