By default, these links are included in the +[[templates]] for each page. If you prefer blog-style +[[plugins/comments]], that is available too. + +### Edit controls + +Wiki admins can lock pages so that only other admins can edit them. Or a +wiki can be set up to allow anyone to edit Discussion pages, but only +registered users to edit other pages. These are just two possibilities, +since page edit controls can be changed via plugins. + +### [[PageHistory]] + +Well, sorta. Rather than implementing YA history browser, it can link to +[[ViewVC]] or the like to browse the history of a wiki page. + +### Full text search + +Ikiwiki can use the xapian search engine to add powerful +full text [[plugins/search]] capabilities to your wiki. + +### Translation via po files + +The [[plugins/po]] plugin allows translating individual wiki pages using +standard `po` files. + +### [[w3mmode]] + +Can be set up so that w3m can be used to browse a wiki and edit pages +without using a web server.
