PIN number
Step 1. Before paying for on-line calculations, please test to determine if our calculations will run on your computer.
You must have cookies 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 Cookie" button below.
If you don't, 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
To activate the Calculate buttons on the entire LMNO Engineering website (all calculations),

How our on-line calculations system works
Once you receive a calculations PIN, go to the LMNO Engineering home
page, https://www.LMNOeng.com, and type it in. A program will automatically check
if your PIN is valid. If the PIN is valid, then a cookie will
be saved to your computer. The cookie indicates how many computers can use your PIN
and the duration purchased. You will not have to re-type the PIN on future visits to our
website unless you use a different computer. If you routinely use different brands of web
browsers (e.g. Firefox, Chrome, Safari, Edge, etc.) on the same computer, each
browser is recognized as a different computer; so try to avoid using different browsers
from the same computer unless you have excess licenses. Your access time (duration) is
determined based on the first date and time you type the PIN into our home page. Date
and time are determined by our server. For example, if you paid for 7 days of access and
type in the PIN on May 2, 2021, at 8:00 AM, then your PIN expires May 9, 2021, at
8:00 AM. It doesn't matter how many times you visit the website during those 7
days. If you type in the same PIN on a second computer on May 4, 2021, at 11:00 AM,
the expiration for the second computer will also be May 9, 2021, at 8:00 AM. If you go
back and forth between web pages, you may need to hit the Refresh button for "All
features enabled" to appear in some browsers.

Cookies
What is a cookie? A cookie is a line of information that is saved to a special file on
your hard disk created by your web browser (Firefox, Chrome, Safari, Edge,
etc.). Most browsers are set to accept cookies automatically. However, if you
are averse to accepting cookies, you can set your browser to accept cookies (click the
advanced button after selecting options or preferences) when you enter your PIN; then you
can turn off cookies. Some people are averse to cookies because they don't want
anything written by a website to their hard disk. Cookies do not spread computer
viruses, and most websites utilize cookies. If you delete your cookie file, you will
be asked to re-enter the PIN and our database will count that as another of your
computer licenses.
