got delete & update to work at the same time in helps & then in credits & faqs
fixed up credits & helps forms; replaced text_area with text_field
cleared remaining side-effects of nesting talks within people
eliminated posted, my_talks, more cleanup
fixed feet; still need to add in tests for them
added in specs for footers; surprisingly helpful
reverted to working version of footer_spec.rb, not able to get complex variable types working in rspec
fixed up create & update buttons so they work more generally:  use new_record? to decide on which button
pre talks push commit:  removed posted_dt, added messages.talk_id, some cleanup on specs & related
folding in precompiled assets & latest database schema pre upload to heroku
