Is there anything I can do while I am waiting on my import to complete?

Yes, you can read the "Getting Started Guide" and begin to make certain updates to Jackrabbit such as creating all your Drop-Down values (if you sent us your class data to be imported and it contained the Session, Location, or Category values, you must create these in your database and the spelling must match EXACTLY). You can begin adding instructors. You can begin adding classes (unless you sent your class data to us to import).
