			Manually apply changes to the posts table?  Your site has more than 100,000 posts.  We <b>strongly recommend</b> that you enable this option and manually run the provided 
			SQL query to alter your posts table in order to prevent timeouts in the web-based upgrader.  If you uncheck this option, it is very possible the upgrader will timeout attempting to
			update your posts table.

			3.3.0 removes the need for a specific Banned Group and uses the built in 'flag' on a per-member basis. However, unless you choose to update all
			members in the current Banned Group as 'banned' they may not appear when searching for banned members in the ACP.
			<br />We recommend you keep this box ticked
