Well, the last few days I suddenly don't have the "memory" again (quite a while since the last time) on the same computer, same browser (not even updated since it last worked earlier this week). Remember me works on another forum site with the same software.Remember me works by dropping a cookie for the site. If you don't get it remembered, you probably have the cookies blocked somehow.
Addendum: It just did it to me again, using Waterfox (a slight modification of Firefox), but I don't have the problem on the regular EAA site (immediately after I had to log into this one again) or on other forums, including one with this software.
Addendum2: For some reason the bookmark I was using went to http, not https -- we had this some time back and I'd forgotten. It works fine with https.
