There are a couple of reasons why a module may not have gotten released.
Start here to find out why:
Step 1: Under "My Groups", click on the "Module Release" under pages.
If modules were scheduled for release, the dates will appear on the module release page.
Step 2: If there is no date listed, add the date you want to release and save.
Step 3: Under the group "Modules" tab, check that the "Deliver modules via email" box is checked.
