Running the latest version of DotNetNuke, version 5.6.1 and cannot find a good answer to why Username and Password cannot be remembered on a DotNetNuke site. This thread goes on about cookies but really misses the point. User 'ptleitch' puts it best when he askes:
"Well thats all fine and dandy. You learn something new everyday. The problem is, my users are submitting issues along the lines of they expect the "remember login" feature to auto-populate the "username" field in the login control, and I've got nothing to tell them other than they're out of luck."
