Maskedcartesian is a new user (created an account April 2006). The main areas where he feels confident enough of his knowledge to edit are in language and literature. His main focus for the moment is on expanding stubs and copy-editing. His editing will move very slowly at least through July 2006.
In this context, "completed work" means that Maskedcartesian's original contribution is uploaded and appears on
Wikipedia. It certainly does not imply that discussion and editing of the page are complete.
