Christopher,

Welcome back! To start training, you're going to need to be placed into an ARTCC. Go to the home page (click the banner above), and login using your VATSIM CID and VATSIM password. Then mouse over My VATUSA on the site menu, and click ARTCC Transfer. Select the ARTCC you'd like to join, and click submit. The ARTCC will then send you further information within the next 72 hours.

VATUSA does not have the academy anymore as it used to in past years. I'm not sure how long you've been at this, so maybe you already knew that. Also, your rating does not force you to control any particular position. Instead, you are allowed to control any position up to and including TWR. If you'd like to stick to DEL or GND or both, feel free to do so. However, I would recommend getting refresher training by your ARTCC training staff when you are placed onto its roster prior to controlling again.
