First time install

1. Get the right version of this plugin! The latest version is designed for WordPress 2.7 and above - use V1.11 for older versions of WordPress down to 2.5
2. Decompress .zip file, retaining file structure.
3. Upload directory wp-cms-post-control and all containing files to the /wp-content/plugins/ directory
4. Activate the plugin through the 'Plugins' menu in WordPress
5. Configure options through Settings > Post Control

NOTE You can just upload the file wp-cms-post-control.php to your /wp-content/plugins/ directory. Hoever, when using the WordPress plugin auto-update, I noticed that it installs it in a folder and deletes a single file install - so I guess it may be more compatible to upload the whole thing within different hosting environments to improve update compatibility.

Update existing install

1. Deactivate Post Control plugin (clears preferences from database on de-activation)
2. Replace old version of wp-cms-post-control directory with new version on server
3. Re-activate it on your plugin management page
4. Configure options through Settings > Post Control

WordPress automatic update

The automatic plugin update feature of WordPress works fine with this plugin. If your server supports it you should certainly use this as it's the easiest way to keep your plugins up-to-date.

You should de-activate the plugin first, as this will ensure that the correct options are set/cleaned-up in the database (especially important as new featues are rolled out to the plugin).

If you have problems, de-activating, then re-activating after update should sort it out for you.
