I am sure you can restrict this somehow..my friend is providing ready made template articles for users which they edit themselves. You could provide specific users with a page by selecting the user as owner from the dropdown when creating the page, and hide the submit sub-menu from specified groups you create, some instructions for this are included. Doing it this way the article owner will not be able to submit, but just edit.
Edit:
Although the pagebreak command is active, which means the article they have can have more pages in it.but only the one article for each user
this is an older version of wfsections Catz new one does this and more I believe
