These automatic subscribe systems cause more trouble than they are worth. Just write to firstname.lastname@example.org with a copy to email@example.com and I’ll add you to the mailing list. Mailings from this site are very rare, and are always in html only format so don’t worry about your maibox getting cluttered because of me. To unsubscribe just send a short request, and you’ll be off the lsit. If the subrsription system appears to be acting up please alert me.
