This is a list of user-side MediaWiki extensions installed at OrthodoxWiki. If you know of another one you'd like to see here, leave a note on the discussion page and we'll see what we can do.
Nice Category List extension
Generates a list of all pages in the category, including subcategories.
Unlike the default category list, the generated list is flat and shows well, even with long page names.
This extension is currently experiencing a bug -- when used with pages of different namespaces, it does not render links correctly. We're working to get this fixed. It works well when all pages are in the default namespace however.
RSS Parser Extension
Please see for details and usage information.
