Use the /whitelist list command to see all whitelists this server currently has. This may include open and closed whitelists. It will also list whitelists you may not qualify for, and show you which requirements need to be fulfilled to sign up for it. If you qualify for a whitelist you can use the /whitelist register command to sign up.
In addition to all available whitelists on the current server, you can also see all whitelists you are successfully registered for on other servers, so you never miss out again. Encourage your projects to put in a launch date for their whitelist, and you have a sweet personal whitelist calendar!
By default your address data is not displayed to ensure your privacy. You can click the button at the bottom of the whitelist list to see your registered addresses.
