I wish to use the PW Yummy Donuts by Peax Webdesign for the title/header of the blog that I am creating using blogger. I understand that personal blogs are not considered commercial use. However, if I have ad space on my blog and receive money from this, will the font being used for the title of the blog be considered commercial use? I have every intention of providing credit for the font in the "about" section of my blog. Looking forward to any replies.
