An upgrade of a script to update Facebook Status

Hello, I have a very simple project. I wrote a script which could update somone's Status on Facebook. It was working for quite a while, but now I am having a few minor problems which need to be fixed. 1. When you enter someones email and password to update his status for the first time, this script works fine. If you immediately try to update a different profile using a different email and pass, the script updates the previous profile. I want this script to be able to update different profiles without conflict. It will be called by another program several times per second, and each time it will be to update a different person's profile. I need it to be able to cope with this without problems. 2. I need another copy of this script which has to be modified so it can update HI5 Status. All of the above applies to this script as well. Attached is the php file with the script. If you feel you can manage this please bid. If you need more details please contact me. Thanks
