I have updated the link: MDS Forums https://www.mds-foundation.org/forums/ so that it should show the "Remember me on each visit" check box on the login page. *It will not show up if you are already logged on. It only show up if you have logged out and then try to visit the forum again. By checking the box you are specifically telling the site to remember you IF YOU DO NOT LOG OUT*
Please note: If you Log out when you are done (which is strongly advisable for any website that you visit for security reasons) then you will be prompted to re-login on the next visit.
When you click the Log out button you specifically tell the site to forget your info. so that is why you need to re-login again on your next visit.
"IF" you did not Log out but instead closed your browser then the next time you visit the forum you "should" be able to get back in automatically. "Should" but not always because your browser, firewall, or other Internet security feature on your computer might clear out your cache, temporary memory, or cookies which might make the browser forget that you were already logged on.
