The Midgard wiki is a bit unusual. When logged in there'll be a hovering menu up in the bar and you can move the cursor over the one that says 'Page'[1] to get to the edit menu.

I'm not particularly fond of it - it's quite different from other wikis, and it looks more or less messy depending on your browser, your default font size, and whatnot. And I tend to forget it - I recalled only when I was reading that page (which is about exactly this).

Fortunately pages with several sections have individual [edit] links, just like mediawiki.

EDIT: [1] or possibly 'Edit Page', the appearance is rather dependent of fonts and the factors I listed
