How to have more than one person to complete same form?

My question is that we want to have more than one person fill out the same form but different parts. Or is there a way to link two forms together that once they have information filled with a common denominator to send an email off.

Yes it is possible to create such workflow based approval form by taking advantage of our "Conditions", "Edit Link", "Get Form Page URL" widget and email alert features.
