Can someone describe what contents the Quarterly Newsletter contains?
Is it available online?
The USCF doesn’t publish a quarterly newsletter.
The TLA Newsletter, which regular adult, young adult and youth members get, comes out every other month, and has the TLA pages from Chess LIfe (and not much else.)
It is not available online, and I don’t know of any plans to put it online. That would be an issue for the Director of Publications, ED or Board to consider.
Regular Scholastic members get a publication that comes out (I believe) three times a year and has TLAs from Chess LIfe for Kids in it. It is not online either.
