Figure 2: Trash
In the filtered view the Trash icon changes to Empty trash. This is your opportunity to delete content.
Check In
The Check In icon in Joomla may not be the kind you know from Foursquare

or other location-
based services. It is a security feature for editing your content. As soon as a user starts editing content,
Joomla locks this content for all other users. The advantage of this behavior is that changes by another
user cannot be overwritten. That's a very convient feature. One big problem, however, appears when the
user editing the content accidentally closes the browser window, allows the session to expire or the power
plant shuts off the power or ... you get my point :-).
Then the content is locked and no one else can edit it!
No one else (except a user with proper permission, e.g. you as the administrator) can check in the
content again to allow others to edit it. Unfortunately, you will only notice unchecked content by a small
lock being displayed near the title (Figure 2) or by a cry for help from one of your users :-).
