Oh you shouldn't have to use MinnowBooster. I would use www.steembottracker.com's tool for delegation. It's very simple. Go here: https://steembottracker.com/delegation.html
Then put in your username and click load. It will allow you to remove delegation, edit delegation, or add delegation.
Ah, thank you thank you! Just sent some over to give this delegation thing a try. Learned so much from your blogs and videos in the past. Thanks again for taking the time today!
