442159 Class Management Site (built off joomla/wordpress/cms)

I'd like a class management site built off of joomla/wordpress/whatever cms you'd like to use It should be a site where teachers can sign up and get their own subdomain or trailing domain ([login to view URL] or [login to view URL]) It should be completely FREE to sign up but automatically show ads on their site (which I should be able to edit). Ad removal option will cost money Site should have most of the features on [login to view URL] (it's essentially a clone I suppose). Unlike classleaf, this is a site ONLY for teachers (classleaf is aimed towards schools) Features ( details and pictures can be found here: [login to view URL]) 1. Easy to use, functional class websites. 2. Simple and clear view of upcoming assignments and events. 3. easy to edit calendar automatically generated from assignments and events. 4. Simple website management homepage for teachers. 5. Clear and easy editing of events, assignments, and attachments. 6. Attach an unlimited amount of files to assignments and pages. 7. Custom, fully editable pages for any purpose. 8. Create email lists for classes to email students all at once. (can upload email lists through .txt, .xml, etc. files) 9. choose from a range of default templates (depending on what cms you are using. one default template is ok, as long as it looks nice)
