A while back we set up Xgrid on two Apple servers and enabled blogs and wikis. Students where able to create a wiki without logging in. We where able to correct that but I was not able to figure out how to delete the wikis that the students made. Our xgrid uses our active directory to authenticate. I am an administrator, but when I log into to the wikiw site, I do not see the option to delete a wiki or blog. We also have wikis that have been created by our teachers that we need to keep. 
Thanks,
