This is to clarify what I actually did.  On my login page, I went to the Login Module’s Settings and set the permissions properties to something other than “All Users”, which now I realize must always be set to “All Users” or it will hide from all users, like it is doing to me now.

I tried, among other things, to borrow someone else’s login page by turning their Login.aspx to my Default.ascx skin… the page loaded but the module was still missing.

Correct me if I am wrong, but doesn’t changing that module, on that page only change an instance of that module, and so if I could place that module on another page, it would be set by default to All Users.   But, how do I do that when I can't login?
