Errors and errors

I just looked back at my last post and see lots of typos, including at
least one that changes the polarity of what was being asserted:

...there isn't an EABer of any sophistication who does see the
concept of "reinforcement" as _requiring_ the specification of alternative
sources...

"does" should be "doesn't"

Since I have so little time to do this without editing before posting,
I think I'd better go back to keeping my email window off the screen
until I really do have the time!

sorry for the noise, y'all,
