This is the same idea that I had for Targets and it resulted in www.targetbunny.btik.com

When you are ready PM me the site and I will drop a link on mine.
If you want to know how I did it I will be happy to pass on the info and experience I had getting this up and running. I have a couple of articles regarding pellets and will be glad to send them to you for your site instead of mine since you are intending to tackle the subject. For example the power calculator on the homepage of targetbunny. I would put it up here but the file size is too big for the BB

Good Luck
Jim
