Hi tm3dantes:
I have attended the GC seminar - in summary, it was helpful and beneficial (I also had worked with the course binder before the actual seminar). Some things to keep in mind:
a) P. Scheele does a super job teaching the essentials in the short time available at the seminar. Sometimes, the available time is not enough to answer detailed questions sufficiently or cover all the aspects of the materials.
b) Coaching by email is available after the seminar; to get a response back may easily take a week.
c) We were promised a questionnaire to provide feedback on the seminar and also indicate if it'd be ok to exchange email addresses, but never got it - we might have deleted it automatically since it may have been enclosed in the frequent promotional mails we've been getting since...
Best regards
