I just got an e-mail in the form of a newsletter from the Pillar Project. It states that the pre-sale will happen sometime between 10 July and 14 July). There will be 40 million tokens available for the pre-sale.
The e-mail emphasizes not sending any ETC to any address yet. An e-mail from Project Pillar will be sent out to pre-sale participants with the ETC address when the pre-sale opens.

The e-mail also emphasizes to Beware of Scams on Twitter and various websites.

Have a great day!
Steem on,
Mike
