I'd like to see a to-do or task list for multi-user blogs.
This would be a central area to create tasks or report issues, such as articles to be written or changes to CSS/themes, etc.
Currently the only way I have seen to do this is to have a document constantly in a draft state where things can be written down.
Long term ideas for this:
*A system to assign tasks to specific users (ie, the guy who deals with style changes or the sports reporter, etc).
*Notifications by email or on login of new tasks for this blog.
*A simple task workflow: New, In Progress, Complete.
