It may also be helpful to know that the standard format for the URL to take you to a specific page looks like this:
So if you make a note of the name-number code for the person's profile, you can just type it into your browser.
You can also save a bookmark in your browser just like any other website.
If there are not a million people with the same name, you can also type the first name and surname into the search boxes at the top of the page, and that will take you to a list. You can order the list by birth date, etc. to make it easier to find someone.
