I found this link today on Codeplex: http://www.codeplex.com/SPDActivities. If you notice there is a workflow condition that allows for the checking of a Sharepoint Group…I guess I am not going to write a custom action or custom workflow, since someone already wrote something and it was sitting right in front of my face. I also noticed another nice function that will start another workflow, rather than auto starting two workflows together. I'm considering e-mailing the author and offering my services to help him update these features in the future. I would love to get my hands dirty after reading half of Workflow in the 2007 Microsoft Office System.
