Share Folders, automatic notification on changes

It would be quite useful for collaboration purposes if I could share a (sub-)Folder to a person or group. When uploading a new document I would not have to explicitly share that document if only I upload it into a folder that is shared already.

In addition, what would be very handy is an automatic e-mail notification to all members sharing this folder. Otherwise I would have to mail the group members separately, and that really wouldn't make sense...

I am considering switching to ZOHO Docs from MS Office Live Workspace mainly because you have implemented folders and subfolders, and due to the excellent integration with Writer, Sheet & co. That works reaaaally fine :-) I hope the sharing functionality can be extended to folders soon....
