Think about providing everyone with access to what’s happening behind the closed doors of your Discord server. Not everyone will read your announcements there or participate in your activities.
That’s why I recommend setting up a Medium.com blog and posting regularly (post something each week) about your project as you move towards whitelisting, wallet submissions, mint day, etc.
Share this via your website, where you can place a teaser and lead people to the full Medium.com article. Make sure to include community metrics if relevant (such as how many people are on the server, how many are whitelisted, how many are participating in activities, how many messages are on the server, etc.). These numbers will prove you have something.
