Automatic Forum Account Logger

I need a script built that can log into accounts from an imported list of forums and bulletin board user accounts. The script should be able to take a list of forum accounts and log into each of them quickly and report errors if the account is not able to be logged into. The script should be able to handle logging into thousand of forums in a timely manner so multi-threading is desired. This script needs to be compatible with logging into all major forum software such as vbulletin and phbb.
