Subject: $sizesSent Conservancy T-Shirt was $HOW

According to our records, the t-shirt of size $sizesSent that you
requested as a Conservancy Supporter was $HOW.
$pingNoGet

Thank you again so much for supporting Conservancy.

We'd really appreciate if you'd post pictures of the shirt on social media
and encourage others to sign up as a Conservancy supporter at
https://sfconservancy.org/supporter/ .  As you can see on that page, we are
in the midst of our annual fundraising drive and seeking to reach a match
donation.  There's a unique opportunity until January 15th to give double
support to Conservancy.  Encouraging others to sign up right now will make a
huge difference!

Sincerely,
-- 
Karen M. Sandler, Executive Director, Software Freedom Conservancy
    and
