Yahoo! Groups provides templates that are great starting points, including a simple phone book, class assignments, and a FAQ table. To create a table:

• From the list on the left of the home page, click Database.
• Click on one of the two Create Table links on the right.
• Select the "empty" template or choose one of the existing templates.
• Fill out the required information for the table, including table information, policies, and columns.
• Finish by clicking Create Table.

Now you can start adding records to your table.

Note: Each group can only have up to 10 tables. Each table can't exceed 1000 rows, or 10 columns.
