Subject: $idsSent{$id} Conservancy T-Shirt was $HOW

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

Thank you again so much for supporting Conservancy.  When we placed our order
for these t-shirts, our shirt supplier (which is itself a 501c3 dedicated to
educating high school kids in New York) sent us the wrong color t-shirt
before appropriately filling the order in a deep gray. We decided to give you
a second shirt in this fun color as an extra thank you for being a Supporter.

The two shirts now feel like a symbol for where we are in our Supporter
program - if each of our Supporters just got a single friend to sign up, we'd
achieve sustainability for all of Conservancy's programs.

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/ .

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