They have been quiet for a long time yes, but I believe for a valid reason. There are many mark off companies who would love to have the technology that $INTK has in their products but don't. Mark off companies (whatever you want to call them) give these types of products a bad rep. This is all building up to filings/PR which should finally get this stock where it should be going... NORTH! The PPS is ridiculously low on this currently.
IMHO $INTK has been very smart getting things set up in advance to bring solid returns for shareholders later. So when they do PR anything it won't be fluff n stuff but solid.
All just my opinion here. Good luck to everyone who is in $INTK.
