Three feature suggestions

Hi there,

In case this forum is still active, we have three feature suggestions based on user feedback:

1. Moving files between media galleries. As our group owners expand their online presence, they find it necessary to move files from one media gallery to another. Currently, this can only be done by manually deleting the file from one gallery and upload it to the other. It would be awesome if a user could move a file to another gallery under his control. I may add this myself, but it would be better if it was part of the baseline product.
2. Teachers are creating private sub-groups for student interactions. At the end of a semester or school year, they need to quickly clear out the group members. Instead of removing them one by one, it would be useful to have the ability to select a batch of users and remove them in one step—perhaps something similar to deleting mail messages from a Gmail inbox by selecting checkboxes next to the affected items and then choosing your action.
3. Blog subscription emails should include an "unsubscribe" link at the bottom. This is particularly necessary when users subscribe anonymously to a blog and don't have the ability to sign in and manage subscriptions.
