We are going to use the supersign for our online application section. We are having an issue getting the signature posted into the form. This might be out of scope but would be greatly appreciated if you could let us know how to get the signature posted into the entries or via email. http://www.epaymentamerica.com/developer/sitemile/
Here is the reply we have from the signature company. They are also looking into this...
You can use the generated sign image $im to save to db or to physical file.
Basically it posts to its form (as suggested in page action tag) then you
can use the $im object as per your needs.
