Hi there.
I've made some modifications to MediaWiki 1.17.0 that others might be interested in. I'd be flattered if some or all of them made it into the official MediaWiki release.
Firstly, I've added links to the W3C HTML validation service hosted by MIT. These show up as 'W3C HTML 5.0' icons next to the 'Powered by MediaWiki' icon at the bottom of the page, and link the user to the HTML validation service. I've found having this feature invaluable in helping me to get my wiki text that includes HTML valid. Unfortunately I've had to disable some features of MediaWiki in order for the validation service to pass the generated HTML. You can read about how I modified MediaWiki for W3C HTML validation at:

Secondly, and more importantly I feel, I've added extended links to the 'section edit' links section. In addition to showing an 'edit' link, I include a 'link' link, and a 'top' link. 'top' just links to #top, nothing remarkable there. 'link' provides a link to the canonical URL for that section. My web-site is available via several domain names, www.progclub.org, progclub.org, progclub.info, etc. I have nominated 'www.progclub.org' as the 'canonical' domain name to be used when publishing links, and nominated 'http' (rather than 'https') as the 'canonical' scheme. In order to support canonical section links I had to make a few changes to the settings files, and update the linker, etc., as explained at:

Anyway, that's it. Thought some of you might like to know. If you like the ideas but don't like the implementation, then please feel free to BYO implementation. Mine's a little bit less than perfect owing to no i18n support and me not knowing the best file to put my functions in. So, I'd be happy if someone else gave my code a spruce up.
Thanks!
John.
