Mornin' y'all,
It seems like adding the RTA label is the theme of the day. I've been doing the same. I've added the meta tag and RTA logo to the index page on all of my sites, and have added the meta tag to most of the static pages. My TGP pages are script generated, so I need to modify all of the appropriate templates. That's next on the list. I'm still debating about whether to retrofit all my existing galleries (huge chore), or whether to just add it to all new galleries as I build them.

is on, help yourself
