HTTPS is now available!

Nothing on this site requires high security, but it is still a good habit to develop. So instead of getting here by using "", I suggest starting with "" instead.

The old, non-secure method (HTTP) will still work because I don't want to break old computers that can not use HTTPS. The exception is the PCjr Web Forum; I'm going to assume that anybody using the web forum has a computer capable of using HTTPS.
