I need a bot that will allow people to sign up for a party guest list via Tweets. The user would submit a tweet looking like this (containing date, name, and number of people):
ATmybot 01/11 Katie 5
When the bot receives a tweet, it follows the user back and sends them a Direct Message saying their submissions has been confirmed. The date, name, and number of guests should be stored in variables for me to access (don't worry about doing anything with the information).
This should all happen immediately, so you will need to handle the notification directly from the Twitter API stream (not constantly refreshing for updates).
Delphi is preferred for this application, but please propose other languages if you'd rather. I would just like to be able to update the code myself afterwards.
