To change your page tagline and the phrase that facebook displays when you link your studio:
1) Visit "Edit Profile" and change your "Tagline" to the sentence/phrase you'd like displayed. Click Save.
2) Visit facebook's developer tools page to clear the cache for your page. http://developers.facebook.com/tools/debug
3) Enter your studio page url into the debugger url bar, and click "Debug"
This will reset the link for your page and your future facebook posts will feature the new tagline.
