If you enjoyed Rational Magic or any of its constituent parts, why not be informed when the next issue or new features go up? All you have to do is e-mail me and tell me that you want to be on a particular mailing list, and I'll put you on immediately. (I don't use so-called free mailing lists because they invariably result in spam.)
Yes, I want to be on the Rational Magic mailing list!
Also note that if you want to be removed from the mailing list, you need merely let me know through the link above, and I will take you off right away.
