Well, for starters, you'll be hard-pressed to find Bob 'answering' any questions on the Forum. His schedule doesn't really permit it. He has actually 'been here' 2x's that I know of in the last 3 years. (I've been 'around' that long ...)
Anyways, Ask Bob here, and see if his helpers can help you. (I'm not an employee of renovateyourworld.com so I can't help you any further.) Other than that, you can peruse the Main WEB site of renovateyourworld.com and see if there are any 'links' to help you. I wish I could do more.
