2603 submission / posting script

a script that will automatically contact certain users (i.e. be able to make a selection) and send them a message. To explain, I make an example: There is a dating site "[login to view URL]". The script will log into the site with a user ID that has been previously signed up, then browse the site and send appropriate ads to the appropriate selection of people. No spamming, just a selection. It must be highly selective, i.e, esp. select for instance by age or region. The script will send then the message to X number of members, then log off. Then, after x amount of time, log in again. Is this possible. Would this work? Any ideas welcome. Anyone has done something aleady?
