Add task regarding Magazine Announcements

[Link Dupont]

Hi Jan,

The Magazine Editors are preparing the EOL article for Fedora 26. We'd 
like to add a new schedule item to prepare the EOL article along with 
the other announcement articles. Can we add a task to the schedule to 
prepare EOL announcement?

I'm looking at the marketing schedule[1] and it looks like it would 
fall in line with some of the "Create GA/Beta Announcements". What's 
the proper procedure to add new tasks to this schedule?
