could it be something that may be bought (just like a Wordpress plug) or perhaps is it custom? let me locate one where i'm able to adjust the lookOrlogo design such as this. also, does anybody have strategies for a light-weight footer or header notification bar that's suitable for aweber?

It seems to become from the company known as Envato: http://envato.com/

Possibly a joint venture partner program or something like that. I am presuming it's custom and never a wordpress plugin.

Whenever you inspect the HTML The thing is the plugin is "promo-strip", there seems to become an item controlling the announcement here is what it is getting used:

 EnvatoAnnouncement.init('promo-strip', 'div.promo-strip h2', 'Close');

Knowing because when the item title is known as after Envato, it appears that it's custom which they authored it.
