The Remember Me feature is an automatic login process which creates a cookie on the hard drive of your computer containing a unique identifier which ASCO.org will utilize to remember you by, thereby avoiding the need to enter username and password upon subsequent visits to ASCO.org. DO NOT select this option if you share this computer with others since transactional, personal, or member only information will be accessible by other users.
To activate the Remember Me option, click the empty check box when signing in to the site. The Remember Me functionality is deactivated at the logout.
