You configure each Aggregator instance simply by specifying the tabbing type (Top, Bottom, Left, Right or Inline), the base CSS style name to apply, and the modules to insert into each 'tab' page.

To place a module within an Aggregator instance, you first create the module on the page in normal fashion. Then you tell Aggregator to include this module (the system then takes it out of the regular page layout and inserts it into an Aggregator tab). At that point, you can still edit the module as well as reposition it (tab sequence) and remove it (back to the regular page layout).

That's all there is to it!
