Announcement: End-of-Year Fundraising Drive In Progress

Our End-Of-Year Fundraising drive is in progress. If you haven't contributed to the operation of the MMD in the last 12 months, this would be a great time to contribute. There's a PayPal link at the bottom of each page on the website.

If you aren't sure when you last contributed, please send me a note using the contact form at the bottom of this page and I'll look you up in my records.

Thank you for your generous support!
Jody

P.S. While your support is needed and appreciated, you do not need to contribute to be a subscriber. If you have subscribed and aren't receiving your Digest, please use the contact form at the bottom of the page and let me know. Thanks!
