Registration - Purchase PIN

Step 1. Before paying for on-line calculations, please test to determine if our calculations will run on your computer.

Cookies must be enabled in your browser to perform the test and to use the calculations after you have paid for them.

Enter the password "test" below (lowercase without the quotes) then return to this page (Registration Page). If the words "Not registered user" change to "All features enabled" and the "Click to Calculate" button works and adds the two numbers, then the calculations will fully run on your computer after entering a purchased PIN number.

Step 2. After testing, be sure to delete the test cookie from your computer by clicking the "Delete Test Cookie" button below.

If you don't delete the test cookie, our home page will say "Welcome Registered User" (since it says that for any cookie set by our server), but none of the calculations will work except the test calculation. You won't be able to enter a purchased PIN until the test cookie is deleted. The test cookie will automatically be deleted after a day.

Step 3. Purchase PIN number for on-line calculations
