When I log in for the first time on many sites, My browser (Netscape) asks if I want it to remember the username and password. If I say, yes, Netscape automatically supplies username and password from then on. None of this has happened here, since the switch to vBulletin. I am thinking that there must be some kind of signal from the site to the browser that tells the browser that the data just entered might need to be remembered. No such signal, here, obviously. I also check in the 'remember me' box, but that almost never works.
