Integrating two diff boards!

Is there a hack if this is possible at all that you could sign up a user on two boards on two different servers?

so for instance when I sign up for this board I'm gonna b registered on another board as well?

ok here's what I'm gonna try to accomplish with a hack I have in mind!

- I will add a check box on the bottom of the registration form giving the user the option to register for another board as well, by default the box will be checked.

- Then after the user receives a successful status registering to your board, it would redirect to the registration form on that other board.

- The registration form on that other board, would be already filled with the previous information the user input on your board (this would be accomplished by using a JavaScript or something similar)

- Then the user submits the second form, and waits for a registration confirmation, fomr that other board, and if course if that nick already exists it would return an VBB message, asking the user to try another nick.

I think this would be a very useful hack, I'm willing to give this a try, but I'm a newbie with both php and VBB, so any help will be appreciated, also if anyone feels like making this hack alone, please do it, I don't care if I had the idea or not, I don't want any credit. The hack working would be enough for me

Also please let me know what you think of this idea!
