Problem with new registration emails

There have been recent problems with new registration emails.  The system was not sending them.  I believe that I have fixed this problem.

If you are a new user, please register according to the instructions.  You should receive a mail almost immediately acknowledging your registration.  If you don't receive this mail within a reasonable time (an hour at the most), then please contact me and we'll take it from there.

My apologies about this.
