Although some site "activities" are easier on a laptop or computer, often it is handy to do quick look-ups on your mobile device.
Most Members prefer to login one time and have the system remember their login information so they do not have to enter username and login each time.
Note on the first image, the red arrow that is pointing to a "Remember Me" box. When you place a check mark in this box, the system will remember you and you will not have to reenter this information on future logins.
If something happens in your phone settings, (and we all know that happens sometimes), you can always tap the "Forgot My Username/Password" below the login button and the system will resend your credentials to you.
After you login, you can choose to view the system in "Mobile Mode" or in "Desktop Mode". See examples below.
The best way to use the system is to always be logged in and them tap the menu icon.
