My undergraduate degree was in Mathematics (University of Dallas, 1971). My core interest is General Systems Theory. My career was mostly in computer programming, however, I also taught English, and high-school mathematics, in China for 9 years. I am currently semi-retired, drawing social security, and working on my various websites. As far as I am concerned, anything I do here is in the Public Domain.

comment Correct usage of the verb "tense"
FWIW: One example, out of many, of how punctuation affects meaning: “Americans like to live in the present tense.” versus “Americans like to live in the present, tense.”

comment How can I tell if a small specialized community is dying or if the long time-scale of activity is natural?
A classic example of a community with a long time-scale, and significant hiatuses, is the Esperanto Movement. Because of impatience, or lack of vision, pundits from time to time declare it to have failed. However, Esperanto keeps outliving its obituary-writers.

comment Ways to organize an ESL course?
@dcsan: Why not email one or two ESL teachers at The New School with this question? Here is the link to find their profiles and email addresses: newschool.edu/directory. (For Division choose “The New School for Public Engagement”, and then for Department choose “English as a Second Language, School of Languages”.) Good luck!

comment Is there an expression for creating something from start to finish (e.g. grain to bread)
BTW: Lerner Publications Company (www.lernerbooks.com) has a large collection of easy readers for young children on the theme of “Discover how one thing becomes another - from Start to Finish” - e.g., From Cane to Sugar, From Cement to Bridge, From Clay to Bricks, From Cloth to American Flag, From Cocoa Bean to Chocolate, and dozens more.
