It's me again.... I had problem with my username so I registered again. What I ment to do is to build a program that help you register in places that there is a limit and one in a day it's open. The program should tell me when the registration is on again

I guess you need to keep track of the version of the page or something and save it in database or somewhere on the persistent media. So any time a page changes you need to modify the value. After that you need to notify your application that a changes has been made. This can be done in different ways. Either your application looks for the version after certain interval and compare current version with the new version OR you need run some kind of notification services.
