Checking User Group Membership in Nintex Workflow

I don’t do much with Nintex yet. If I’m able to do my processing with the SharePoint Designer Workflow I will. Unfortunately one thing that can’t be done in SharePoint Designer (OTB) is check if a user belongs to a SharePoint Group. It’s not that straight-forward in Nintex either. Tom O’Connor at CUBE4 wrote a great post instucting exactly how to do it: Nintex: Checking if a user is a member of a SharePoint group.
