Note Submitter: randall dot reynolds at rightnow dot com ---- The instructions say, use \\\\ (four backslashes) to represent a backslash. You can shorthand this and use \\\ (three backslashes) to represent a backslash, because of the way the parsers read it. It appears the double escaping is required because the string is parsed twice, once by PHP and once by the regular expression generator. Thus it is expected that the PHP parser turns both instances above into \\ (two backslashes) for the PCRE parser.
