The things about using ' remember me' is don't use it on a public computer or one you share and want to keep your accounts private. A person can get your info or get in your accounts by using remember me, If it remembers you then you don't have to log in, but neither does another person that uses it. So I prefer to log in with it unchecked.
"Remember Me" is optional. You don't have to constantly press it unless you want the system to remember your computer every time your IP logs into the system. Believe me, I used to think I had to use 'Remember Me' all the time until I realized what its specific use was.
2..... What is the difference between " acc. restricted " and " former member ' ?
