Users who are communally editing page attachments are not notified that the file is being updated by other users. The simplest way to address this issue is to add a checkout field to each file on the attachments tab.

• Each attachment has a checkout username and checkout timestamp associated with it.
• Each attachment has the options to Edit, Remove or Check Out. If a user has checked out a file, the link becomes Check In for that user only.
• The user link is to their email address eg [John User|john@company.com]. Mousing over a user shows the date the checkout was performed eg Since 17 Dec 06.
• Checkouts are automatically removed with a user uploads the file or clicks Check In.
• Checkout don't expire and are removed by a user checking out a file then checking it back in.
• There is no file locking.
• Only one user is listed as having a file checked out, so checking a file out when another user has checked it out overwrites the owner.
