Procedure to address a list of issues

Hi PG. Larry here, writing for Fred.
“I have a list of a number of questions and issues that seem to be recurring since I switched from WL 5 to 9, 10, 11 and now 12. What would be the best way to submit and address them?
One at a time on this forum, or via a personal contact? I can be contacted via my Website if you are interested.

Thanks so much,
Fred”

One at a time, and only for WaveLab 12.
