I have around 750 SP sites set up. Each site was set up with unique permissions. SP 2007 helpfully created 3 SharePoint groups (' site members', 'site visitors', and 'site owners') for each site. I don't use the SP groups as have created my own automatically populated active directory groups. I have created some SP groups to use as audiences for web parts. Every time I want to edit the membership of these groups, I have to wade through the 750*3 SP groups I don't use. Now I'm trying to delete all of the extraneous SP groups. Surely there's a quicker way than having to go through each one and delete individually?
