Thanks for the suggestion Pete. I want to do this survey form in AwareIM and I think I can use the guest account so when I email them the URL link, it would have all the guest login info to the correct domain.
However, on the URL link for AwareM, is it possible to include an edit form and a particular business object record? For example if Customer-A has a completed Order#1, when Customer-A clicks on the URL link (with guest login and all) that I would email him, I want it to go straight to an edit form o the business object for Order#1.
