You sir clearly should get with the times. It is perfectly legal for a company to send out tweets about upcoming events. Using your train of logic I guess companies should still have to mail a paper copy of PR's to shareholder because what if the shareholder doesn't have a computer...LOL
The original tweet came from AMBS not GC. And to me reads data will be released about MANF and an update on LP-002.
