We are interested in getting into the educational seminar business for
the public, including delivery via a variety of media (in person,
online, and via telephone conference or braodcast).  We need to
determine what specialized industry software and/or services are
available to help us manage (confirmations, registrations,
cancellations, scheduling, posting new info on course description &
syllabi, etc) and market (procure attendees) educational seminars.

Hi! Thanks for the question.

Online event registration software from SignUp4 can also assist you in
communicating with potential attendees, getting their registration

Thank you very much for your efforts in answering this question.

However, it is one that I asked almost THREE YEARS ago ... so at this
time we have no use for the information, and as such I regret that I
cannot offer to pay you for your time.  (Please check the posting date
to confirm).

Hi glennjers-ga!

The new post above by signup4-ga is just a comment and is free. So you
are not charged for an extra fee.

Thanks!
