I'm unsure as to what exactly they are. Can anyone write one, or can only certain members?

On the old layout, all members used to be able to write articles, about whatever they wanted.
When the new layout was introduced not too long ago, this feature got taken down. Supposedly they plan to bring it back, though we're not quite sure when. They're probably updating it to go along with the rest of the website, so we'll just have to wait for now!0
