Help needed on point system

Hi all, I am relatively new to php and mysql and would appreciate any help you can provide. Here is the task: I need to have a point system added to my site. What I would like is when a user logs in they will get 1000 points. But they only get it once per day. I am the kind of person that cannot learn from just reading from a book. I have bought plenty on php and mysql. I can however learn by seeing things work. I have tried to find a script that has a way to add points to a database but cannot find one. I am not asking anyone to write the whole code but help get me started. I am running: Xitami on WinME, PHP 4.06 and Mysql 3.23.43 win binary. If anyone is willing to help I will provide a database dump and any part or the script you will need. I would give the info now except I don't know what parts will be needed. Thanks for any help Regards Jerry
