I've been interested in finding an app for my N900 that will do something similar to this program. Basically it means someone can communicate via SMS with you with a specified code before the message (br in the case of the program linked) and an automated response is generated from the phone via SMS.

Why would I want this? Well, as a teacher I've found it a useful way of pushing material to my students on a weekly basis. I teach English as a foreign language students and this is a way for me to send weekly vocabulary lists to them without having to remember to do it myself. When they want them, they just text me with the specified code and they get the list every week.

It would be great if something like this was possible (or even already available!) on the N900. I'm not particularly technically-minded, so don't know how to find out this information. Does anyone know if this kind of program is possible/available on the N900?
