My Mom who now lives with me would like to become a member here. Can there be two accounts using the same computer? Does she initially need her own email address?
Only one of us can be logged in at the same time. correct?
Well, I hope it is possible.

You can do that, and your guesses were correct. She'll need her own email address (she can get a free one at gmail.com).

You will need to logout (the link is in the footer of every page of the site) so she can login. When she's done, she'll simply logout.

Just remember your passwords (can be changed by your profile) and you shouldn't have any trouble.

I seldom log out, and I was at my daughter's house all last week, and could not remember where the logout was now I know...again.

Another alternative would be to have two browsers. You could use one to access ATP and she could use the other, that way no one would have to log in and out. You could both use the preferred browser for your everyday use and one of you use the secondary browser just to access ATP.

If we're going to go the route of complex setups (which can be great), another option is that Chrome allows you to create different profiles in the same browser.

Thank you for the quick reply. Glad to know we can make that work. I think she will enjoy being active here. and I probably will learn a few more thing or twos from her as I have throughout my life.

Think we will pass on the complex set ups and concentrate on remembering our passwords!
