One embodiment is a method including producing a form having one or more data entry components and at least one signature block component, selecting assignee users of the content sharing platform, providing the form to the selected assignee users, enabling these users to enter data and sign the form, and storing the assignee users' data in a data structure which is separate from the form, where the data structure includes a record for each assignee user, the record containing data entered by the user and electronic signature data for the user. The data structure is protected in the same manner as other data in the collaborative content sharing platform and may be accessible by some users, but not others, in accordance with their respective roles and authorizations.
