ScreenCrush found an interesting note supposedly written by J.J. Abrams himslef. Abrams wrote the note to inspire everyone working on the film. Don't worry there are no spoilers...
It looks like the note was written on paper similar to the one used for the Episode 7 script (unconfirmed):
Dearest Cast and Crew, What an honor it is to work beside all of you, on Star Wars Ep VII. I can’t thank you enough, for all work past and future. Let’s take good care of not just ourselves, but of each other. Amazing, but true: the world awaits this film. Let’s give ‘em something GREAT. xo JJ
I'm not sure how legit this is because ScreenCrush never mentioned where they got this piece from. Might be legit, might be not but surely it sounds cool!
The big printed text across the page reads Dawn Gilliam - J.J. Abrams script supervisor. This supports the speculations that this was indeed the Episode 7 script:
Thanks to Unknown from the comment section for the find.
