Create a new task. Fill in at least the subject area. Click on recurrance,
select a recurrance pattern at the top of the screen. On the bottom of the
window select an end date - how long you want to recurrance to carry on.
Clcik OK, Save and Close. If you are looking at your task list, the future
tasks may not show up because of the View setting you have in place - You
may be looking at only Active Tasks.
Hope that helps.
