This page contains both user comments and a form to submit additional user comments (give feedback, provide additional information, new references, cites, etc.). Posters' identities are not anonymous and comments are limited to about one page (2,000 bytes) per comment. By posting, you agree that any material posted can be used by me (Ivo Welch) to integrate into the main page at my discretion. After submitting, your comments become immediately available to the next reader at the end of this file (refresh your browser to force reload of this page). Please be aware that this file may be purged from time to time, especially when the purpose of the submissions becomes integrated into the main text (which invoked this feedback form.)
