Can you put a user's gallery into tachy goes to coventry?
 

You know how with vbulletin, you can enter a user id in the admin area, and put a user's posts into tachy goes to coventry, and they are all temporarily hidden? Can you do that with Photopost?

We use this feature at our site as an "Emergency Hide" feature. We have times where members will suddenly freak, because a friend, ex-b/f, parent, co-worker, rabbi, etc, someone in her RL has stumbled across the site, and she does not want them to read her posts - so users have the ability to put themselves into 'emergency hide' which then instantly hides all their posts, while they figure out what to do, or what to tell the person. Sometimes they keep them hidden for a few days, sometimes a few weeks or even a month, depending on who found their posts and and why.

I'd like to be able to offer this option for the photo gallery too.

This way it gives the member security that in case something like that happens, they can hide all their pictures right away.. It also helps in the case where a user has a fight with anyother user, gets mad, wants to delete all their info and leave, but then in a few days cools down and comes back, and then is upset because they can't get all their deleted data back. So by letting users put themselves into or out of emergency hide at will, it lets them have control over their data without panic or unnecessary or later regretted deleting.

I guess that a user could probably also just change all their albums to private too? Can you switch an album from public to private once it is already established?

There is no functionality like this. Only thing you can do is move all their photos to some category no one but you can do.

How about changing an album's status once it is created from public to private or vice versa?

Users can do this by editing their albums sure.
