We have some custom built comments (ones tied to custom post types, that we can't integrate with WP's comment system). But we want to filter the comments when they are submitted the way WP does and also save them to the DB the way WP does so everything is filtered (not really for spam), basically sanitized for security purposes but also if we get the pretty
tags and emoticons that WP will do. We need this to be safe for front end and backend. As I was able to put in tags and have tested with SQL injections and also want to make sure that it doesnt get all the wierd \n \r\n garbage.
