Q: Why Does Internet Explorer Keep Logging Me Out?

Most likely due to security settings.  Click Tools -> Options.  From the tabs along the top of the window that opens, select Privacy.  Click the Advanced button.  Check the "Override automatic cookie handling" box and then check the "Always allow session cookies."

The blocking of cookies is something browser manufacturers allow to placate the paranoid, since cookies are not executable code.  GuildPortal uses cookies only to maintain your session while you're online, and to make it possible to automatically log in (if you so choose) between sessions.
