Everything on the Chief Shepherd is totally free. There is no charge for anything. You must register in order to see some of the content but even the registration is free. You will NOT receive any enhanced benefits as a result of any donation. As a registered user, you have full access to the public content here.
However, if you find the content valuable, you are welcome to make a donation of any amount to help with the administrative costs. AGAIN, THERE IS NO REQUIREMENT TO DO SO. If you choose to make a donation, a button is provided on the home page.
If you make a donation it is NOT TAX DEDUCTIBLE. The site is NOT set up with the IRS to allow you to claim a deduction on your taxes.
I am very pleased that you are participating on the site and I trust that it is beneficial to you. And, if you do make a donation, I offer my thanks.
