Disable Post Locking

Disables automatic post locking so multiple users can open the same post in the administration panel.

Warning: Post locking was an addition to WordPress in order to prevent such bugs as overwritten autosaves (coming from multiple authors), and of course to prevent accidentally overwriting another user's changes with older content. These are often never problems for many users, and you should likely be communicating with your fellow editors when making changes anyway. This plugin makes the choice of relying on the latter rather than post locking, so you may run into those problems again.
