Hello Webmasters of PTR sites, I was hoping you could help me with a calculator I have been working on. I am making a sustanability calculator that is based on advertising rates. Ofcourse, this is a more advanced method of finding out how good the payouts are going to be, but a good one.

First I need you to post a nice sustainable advertising price using an email to 500 members at 1/4 cent. This means a price you think would make for a good site, and no future dept problems, please don't make it too outrageous.

Second post your site's advertising rate using an email to 500 at 1/4 cent, if you have one. If you don't just post a one that is divisable into those values.

Also I would like to know if you WMs change your advertising prices when you get more and more members. If so, raise or lower?

ALSO, if you know of a site/program that already calculates this, please direct me there .

THANKS.
