I downloaded multisite privacy and uploaded the unziped folder sitewide-privacy-options to wp-content/pluging/ in WP 3.1.2. I see in the folder a folder for languages a file called changelog.txt and a file called sitewide-privacy-opti (that is all). The sitewide-privacy-options folder is listed with my other plugins but I do not see any form plugin in my dashboards. Would it be some place else or did it not install?
Have a great day.
