Getting message "Bandwidth limit exceeded. Please wait to transact or power up"?

For some time now I've effectively been unable to use my steemit account. I kept getting the error message: "Bandwidth limit exceeded. Please wait to transact or power up". I would wait for a few days and try again.

I just recently found out this can happen if you've completely powered down. I was able to 'unlock' my account by buying a small amount of Steem power on steemit.com using Ethereum.

Just wanted to share this in case anyone else was experiencing this as well. Cheers.
