Does NKJV count?
No seriously, if you like the NKJV that is fine, you can join, all the Caucus asks is when posting scripture, use the KJB, that way when people are discussing topics, there is no confusion as to what is being relayed.
There's many Bible versions out there, and by keeping the main focus on one standard, everyone can be on the same page in the forum.
Will people post other version from time to time? Probably, but again the main focus will be the KJB.
