AM> CFRG chairs are starting a poll, containing 2 initial questions:
AM> Q1: Should CFRG recommend a curve at the 192-bit security level?

No.

AM> Q2: Should CFRG recommend a curve at the 256-bit security level?

No.

Something in between, with better than 200 security and good performance,
would be better than targeting 192 or 256.
