You may notice that some projects have a subdomain like dev.mirror.xyz. Currently, the Mirror core team selects a few top writers each week and rewards them with a $WRITE token which gives access to register a subdomain and entry into the Mirror DAO. In the future, the Mirror core team plans to hand over this selection process to the Mirror DAO so it's a fully community-led process.
In the meantime, if you'd like to be considered to receive a $WRITE token, join our Discord and post your project URL in the #pitch-spotlight-project channel.
Once you've received a $WRITE token, you can go to the settings page in your dashboard (https://mirror.xyz/dashboard/settings/accounts), scroll to the “$WRITE Token” section, click the "Burn" button, and confirm the transaction.
