It appears that Google has changed its security procedures for email set-up through Google Apps. This thus obsoletes the WordPress set-up instructions [ setup your email through Google Apps for Domains: http://en.support.wordpress.com/domain-mapping/google-apps-email/ ].
Specifically, the verification codes generated by Google now look nothing like those in the example -- and those on the actual DNS settings page. The codes actually generated by Google were rejected by the DNS Records Page.
Without access to my site's home page code as Google recommends, and with no ftp access to the actual site, as Google suggests, I have no way to set up email connectivity for my newly mapped domain on WordPress.com. YIKES!
P.S. The new format is a text string [ changed a bit here ] : google-site-verification=W4b23NEA2XjasreSwASDFLKJEQytr8oiu_n78r-PtR for pasting in the DNS record.
The blog I need help with is growanddevelop.com.
