I just need to follow up to my orignial question to make sure I am making sense. I wondered if there was intelligence in forms central to query incoming data- ie. pull a report on what email addresses viewed a form. An analogy of the type of report would be if you wanted to pull a report on incoming calls to your cell phone- for this type of query you would not need to know who your outgoing calls were- you would be trying to determine incoming information. Thanks again for the help.
If you asked for email address in your form then you would know (its in the response table). If you didn't ask for an email then there is no way to know.
