Importing users from a flat file
 

Hello,

I own a vBulletin community with some thousand users. Meanwhile I acquired a website with some thousand users and I want to merge them in my vBulletin installation. The users are stored in a flat file with the format . My ideia is to merge them automatically with some random password that I'll send to them. Even though I have the necessary MySQL/PHP skills, I'm not familiar with vBulletin database, so I would like to know what is minimal data I need to insert and how to encrypt the password.

Thanks for any help
