Limit Post Revisions Network Option

A Multisite Network plugin to add Network->Settings to limit, or disable, the number of post revisions and set the post autosave interval.

Notes

I based the default plugin values for the constants AUTOSAVE_INTERVAL and WP_POST_REVISIONS on the discussion here: http://wpmututorials.com/how-to/managing-autosavepost-revisions/

This section describes how to install the plugin and get it working.

1. Upload the plugin to your blog, Network Activate it
2. Go to Network Admin->Settings to set “Post Revisions” and “Autosave Interval”.

• Do I need this plugin if I have WP_POST_REVISIONS and AUTOSAVE_INTERVAL defined in my wp-config.php? No.
• Will this plugin delete existing post revisions? No. It defines the constant WP_POST_REVISIONS and WordPress takes care of the rest.
• Should I set the Autosave Interval to 0? No, I recommend 300, the WP default is 60.
