As an instructor you may want to create a sign-up sheet to allow students to sign-up for office-hour slots, or to sign up for topics for an assignment, or for meetings with an advisor or conference seats, etc.
The best way to accomplish this is to add a Wiki to your course. A Wiki is a page or set of pages that can be viewed and edited/filled-out by students.
Create a sign-up sheet on the first page of the Wiki with visible slots that the students can sign up for. The students can then come and sign their names in the slots by editing the Wiki page.
