A mainspace edit is a type of edit where you have successfully edit an article. Posts from forums, blogs, blog creation, template edit and the like are not considered as mainspace. To get your mainspace edit; select any article you see that contains an error. Click the edit button or tap it (if you are on an iOS or Android tab or smartphone), then begin making changes. Once done, publish your edit.

If you want to get to the rank of Chat Moderator you need to have 500 (I think) mainspace edits and must be very active on chat at all times. It requires extensive time-frame; to ensure you are fit to be one.
