Hello Lee,
Actually, the place to post your own writing is in the “Share Your Work” corner, which is a sub-forum within the “Conversation with a Thousand Faces” forum at the bottom of COHO’s main page. Here is a link to that section. If you can’t unlock the Google Doc, you might try copying-and-pasting it (follow the link, scroll to the bottom of the page, type “The Homeless Man” into the topic area, and paste your essay into the field provided).
Might need some formatting, but you can always work on that after it’s up.
