We have entirely disabled editing of the current MindTouch based wiki, without enabling the automatic redirection to Kuma, while we deal with a technical issue caused by our script that was automatically migrating every edit on the MindTouch site to Kuma. Once that is resolved, we should be able to enable the automatic redirects of edits to Kuma.
We apologize for the inconvenience, and we will try to get things up and running as expected as soon as possible!
About Eric Shepherd
Back in the early days of my career, I was a coder for computer games; if you search little-known Mac titles published by companies including Interplay/MacPlay, MGM Interactive, and Logicware, you'll see my name. Eventually, that work got old and I became a technical writer. Now I'm the developer documentation team lead at Mozilla.
