wpStickies made with perfect integration with your WordPress site, this made us possible for such important settings that user permissions. You can control who can create or modify stickies.
If you want to share your stickies administration with other users, you can specify a custom capability for these users. They won't be able to modify plugin settings if you don't enabled the option for this, but they still will be able to review all the changes and accept or reject stickies on your pending list. You can find all the available capabilities on this page.
The plugin is intelligent, so if you are an administrator, all changes will take place immidiatelly without any confirmation.
The plugin created a new user group for you, called "wpStickies admins". The members of this group has basic capabilities, much like the subscripbers. They aren't special, they just can create stickies if you choose it in your permission settings.
Rejecting a pending sticky or removing any of them won't delete it immidiatelly. These stickies still will be available in your "Restore" tab under the "Stickies" page. You can decide that you either restore or delete them permantently. In the meantime, they will be invisible.
