Abstract: A system for providing users with electronic access to multiple electronic collaboration services via a single electronic work center with a single user home page is disclosed that provides routing of users amongst multiple electronic work centers, each with access to a centralized electronic signature service. User information remains accessible from the user's home page while the user accessed functionality in other work centers can be controlled according to the access and authority credentials and rules specified by each third party work center administrator. In addition, electronic signatures can be applied in the work center environment, including via integrated audio and web conferencing with document management. The work center environment can be used to manage an electronic document to be electronically signed by any number of individuals in remote locations, with any of these signings being performed on a single computer in a single location hosted by an independent third.
