Peter,
Your offer is generous at the very least. Perhaps even philanthropic.
I suspect that the reason many come to the lisp forums may be that there are few other options.
Nonetheless, the type of seminar you offer will always provide better and longer lasting results.
So, if you can pull this together, count me in. Good luck.
Furthermore, a word to the young of our community, if I may:
"Opportunity has knocked"
Invest in yourself, the $200 will seem a pittance a year from now, when you've added
these new strings to your bow, and developed routines like the masters here or other similar sites. You will be happy to do it again; but it may not be offered again.
