I'm receiving emails at least twice a week on someone wanting to advertise on this website. Since I'm receiving a high volume of emails on this particular subject, I decided to dedicate a page to help answer questions. Although this website is worth just a little bit of money, this site receives a very low total on average of 1,000 visitors per year.
Since this is my personal website, I want to keep it as commercial free as possible. The only exception that I make is who I donate to every month. I feel since they are part of my monthly charitable contributions, they have a place on my website as well.
I hope this helped answer your questions and will reduce my emails relating to getting space on this site.
Thanks for your understanding.
