One way is to create or forward an email, especially a compelling, current event/ viral email is best, to everyone in your mailbox. Insert a pronouncement into it:
Get in early... "buy POETF stock soon!" or "buy PTK stock soon!"and a link such as the one that follows along in the email, with the intention that others will forward it to others in their mailbox. I see the following transcript to be a compelling intro to POET: https://agoracom.com/ir/POETTechnologies/forums/discussion/topics/751786-a-christmas-joint-venture-flip-chip-video-transcript/messages/2294737 

You can also send the transcript to some industry/technical Journalist types, etc. and don't be shy to tell them to: Get in early... buy POETF soon! Don't miss the boat!
