What is Maverick status?
This means you invested above average in Splinterlands packs. We reward that with a Discord channel only Mavericks can enter and a special role in Discord, that gives you the purple color.
I got 1000 packs how do I activate it?
You will still need to register the role in Discord channel registration with the $register <hive name> command. Then you will get a message to make a small Hive transfer to sm-voter with a code from Discord to confirm your identity.
Be aware that only packs that you bought in the shop (not from a 3rd party) on 1 account count towards these 1000 required packs. In Discord channel sm-voters_hut you can check your current amount of packs with $packs <hive name>.
