Have new computer and now I have to sign in every time I log on??????

 

A few things.

1) Make sure you are selecting the "Remember Me" box when you enter your username or password. If not, you will only get a session based login - meaning you will lose your username/password credentials if you exist your browser or 20 minutes of inactivity from your account passes.

2) If number 1 is being done, then you either have:
A) A corrupt cookie in your browser. This is fairly common and usually isolated to a specific site (at a time). Simply delete the ThirdGen.org cookies in your browser and revisit the website. How you do this depends on the browser you're using. It is recommended you specifically delete the ThirdGen.org cookies rather than delete all cookies so that you don't lose all your preferences and username/password credentials for all other sites.
B) You have a 3rd party software that is blocking ThirdGen.org from setting a cookie in your browser.
C) Your browser is rejecting cookies
