Good questions! The title will cost 10 CC and the title will unlock per character. There is also a collections unlock associated with it which will cost 5 CC. Also for those who 10 CC is "too rich for my blood" the item, like all CM items, will be tradeable so you will likely see some popping up on your local GTN.
If this title is going to be widely available to everyone how is it considered "subscriber appreciation" then?
Whatever. Thanks for the extra stipend - that's at least something useful.
