First, you could read the former messages on SG20 (low volume)
Then there are a few important papers: https://wg21.link/p1231
(the founding paper of SG20)
https://wg21.link/p1389 (standing paper)
https://wg21.link/p1725 (progressing from p1389) 
A list of modules and topics for C++ guidelines

I am currently working with others on a document about how to write a guideline module.  We already have two topic guidelines in the works:
A template: https://github.com/cplusplus/SG20/blob/master/skeleton.md
About User Defined Literals: https://github.com/cplusplus/SG20/blob/user-defined-literals/functions/user-defined-literals.md
About Copy Semantics: https://github.com/cplusplus/SG20/blob/copy-semantics/object-model/copy-semantics.md

Good morning.

I just joined the SG20 mailing list.

I am an Assistant Professor of Instruction in computer science at The University of Texas at Austin in Austin, TX.

I've been teaching CS371p: Object-Oriented Programming in C++ there since 1995, and I've been teaching C++ to industry since 1989.

How can I get more involved with SG20?
