[closed] e-signature

Hi,

Does anyone have some experience with using E-signature within the work items in RTC 2.0.0.1? On which way is it functioning?
I tried to make Approval, and added Approver. I also wrote the e-signature bellow. Does that approver must enter the same e-signature on approving work item, or something else? I put on Operation Behavior that the work item can not be saved until the valid e-signature is entered.

Thanks,
