Carlin,
It seems like a wrong approach to submit more than one form. By virtue a form is sort of a "domain" of information. If you have seperate forms they likely should be submitted seperately. There are ways to combine information so the form is split up into pages or even "tabs" for example of how to do it on one page. I am not saying that this is always possible (there are always client and boss issues) but it would be more ideal to approach it that way IMO.
