Not with GVMax. I have written custom apps for people that have done that though.
For example a smoke cessation program that contained a number users could SMS a message to and which
would send an SMS reply that rotated depending on the user who sent the SMS. Also did a magic program that would stop sending SMS replies after a number of SMS were received by a given user.
If if you think that is something you would want me to develop for you send me a private email at gvmax at gvmax.com and we can discuss it.
