Hi Charlene,
It sounds like you haven't found the Timeline form. Enroll yourself as a Director (using the Conference Management tools), go to User Home, and follow the Director link. There you'll find a Timeline link to configure dates when submissions are accepted etc.
Once the initial release of OCS 2.0 is complete, we'll be working hard to fine-tune some of the spots in the user interface where we find people are getting lost (particularly roles like Authors and Reviewers who don't necessarily have a lot of familiarity with the system).
Regards,
Alec Smecher
