I have been using DT Register since my online business began, more than five years ago and the only thing I really think I want for Xmas is the ability to integrate SMS texting thru the reservation system.
With the market's smartphone technology, EMAILs are really a dead thing of the past. Even my 60+ year old clients text me to cancel or inquire about a sessions/reservation.
Please consider a) Reminder messages, b)confirmation messages and even c) cancellations via text.....soon!
