Register multiple users from one page?

[krit]

Hi guys,

I'm looking to set up a system that will allow multiple registrations to occur from the one page. The idea being that i want a person to be able to register x no of friends all at once from the next page after they initially register themselves(possibly with passwords being created randomly rather than being entered for the friends). Not sure if this is doable using a relatively simple approach or if it will require a lot of work. Any feedback would be appreciated greatly.

Cheers
Krit
