If you’re involved with a game store that has run D&D previously, any Magic: The Gathering tournaments, or Friday Night Magic, the process for getting involved is similar. You schedule events on the Wizards Events Reporter and Wizards of the Coast will email you a link to download adventures, along with a password.
If your store has never scheduled Wizards of the Coast events before, first, the store must join the Wizards Play Network. Then, download the Wizards Event Reporter(Windows only) to schedule events. After you schedule events, Wizards of the Coast will email you a link to download adventures. You can always stay abreast of events by viewing current available events.
Next, create promotional items, announce the events to your local community, and get ready for the fun! Some flashy flyers or notecard-sized handouts can really spread the word about your event very quickly.
As players sit down at your table, record their DCI numbers. If they do not have a DCI number they can get one at dci.wizards.com
