Hello,

Is there any option to change item permissions from Registered to Public in batch?!

I use to update my items first in registered mode for me and if everything is OK, to change for public....

But it is a lot of job for many; now I will need to change permissions for some 60 items - it means - to open each item, change, close, open next , etc......
a lot of job, when I have often to add some 20-60 items.....

may be there is some shortcut?

I'm afraid that there is no such option to the current version. You will have to change them through a query to your database.
