I'm writing an Appengine app: one of its duties is to email all the users every night (I know that I'll have to enable billing to email many users -- that's no problem). I'm just worried about the 30-second request limit; if I have thousands of users and I have to mail them all a daily reminder, won't that limit be hit sometime soon? ...
So i've just finished the google app engine greetings tutorial. All well so far. I then decided to try and add a new datastore model and then set it in the existing handler.
