New User Account for user:

I have two fields in the form of resources that are:

First Name

Last Name

I would like to initiate on the change of either of those fields something to the effect of {in pseudocode}:

fullName = Firstname + " " + Lastname

subject=Concatenate(subject$, fullName)

Can I do that? I've resently loaded python onto my server and while I have experience with python scripting I haven't yet played with how SDP and Python interact.

Thanks for any advice you can give.
