Web Based Twitter Software Needs Updating

I have a web based twitter friend adder that is needing some updating. It has worked fully in the past, but I have not updated it almost a year. I am needing to get this updated with the new twitter code so that everything works properly. The features the program has are... Automatic friend following: the script followers users based on keyword. I am needing this to be updated to function properly. Automatic Scheduled tweets: have a status update post in the future. Account management: right now the system is set to work with oauth. But is this still required by twitter? or can we switch it to regular HTML again. Whichever works more stable. That is about it. Just needing these updated. The features are already developed.
