If you do it on the first of February or the first of any month you will earn a Hive Buzz Power Up Helper Bee Badge which, when I earned mine, I thought was very cool!😎 
Just go to HiveBuzz.me and enter your account name.
If you would like to Power Up another account you can also do this at any time.
When you click power up it will have your account name on the left and the account you're powering up on the right.
You can change the account on your right to any account that you want to power up!
Happy Hiving!
