We throw around a lot of terms when we talk about federated wiki that come from a variety of sources. Here we look at the sources and mention the most common names they provide.
You can wander all day in the federation, and it's easy to get sidetracked. Here we link you directly to the things you must be do/be able to do before the March Happening, in a nice linear style. You can still wander if you want, but if you want to do the minimum, go through this list, skip the byways, and you will be set.
