The TNIV committee (the CBT) is always willing to examine specific suggestions for improvements. Just last year we examined dozens of Wayne's suggestions (and accepted many).
Referring back to earlier posts [in discussion lists] would not be helpful for me, since I don't really have the time to read through archives. However, if you have specific suggestions for improvements, and want to cut and paste your exegetical arguments from past posts for these suggestions into a list of proposals, I would be more than happy to present these to the committee.
List the present reading of the TNIV, the proposed reading, and then the argument for it. [WL:Use the webpage form provided for your suggestions.]
As Wayne noted, December 31 is the latest we can receive proposals. Many years we do not get to all the proposals at our June meeting, but they are kept in a chronological list when they are received and will eventually be examined by the committee.
Hope this helps.
