I didn’t see this posted anywhere on the main page of the website, and it was only when I went to the membership store that I found it, but . . .
USCF is currently offering a one-year promotional membership for $19.72 (online only) or $31.72 (Chess Life print magazine) through August 31st. People whose membership expired in 2011 or earlier are eligible for this promotion. Please tell your friends who are former members!
This looks to be the membership that celebrates the Fischer - Spassky 40th anniversary (hence the 1972 price tag.) See viewtopic.php?f=5&t=17566&p=241538#p241538 although I’ve also heard this mentioned elsewhere.
I beleive this went out in an e-mail to former memebrs for whom we have a valid e-mail address.
I also received it, so it may have gone to affiliates as well.
There was an email blast that went out earlier today, but only to lapsed members, not to current members or affiliates.
However, if you ever used your email address on a membership for someone else, that could explain why you got a copy.
Look at the disclaimer block at the end, it will tell you the USCF ID and email address it was intended for.
