Redirecting data

[_Nate_]

I have been tasked with an interesting task.

There is a web site that has dynamic forms (namely, the SecondLife.com registration page: the 'last name' form changes frequently). My employers would like me to design a web page that allows 'remote account creation' of a second life account from their own web page.

I'm pretty much the 'all purpose programmer', and I've done a fair amount of HTML / CSS work and a bit of javascript, but I don't really know where to begin.

How do I do the following?

a) Get the objects in their forms (these change frequently)
b) make a web page with a form that has the objects retrieved in a)
c) make the form submit to the same location as the forms looked at in a)

I'm pretty sure that to do c), I just make the submit of my forms point to the same place as the submit of the SecondLife forms, but can someone get me pointed in the right direction for a) and b)?

Thanks.
