When you absolutely KNOW substantial revenues are coming in this year then you hold until they come in and then make your decision to take profits. I am talking about E-Mail Frequency and the CEO's remarks that his company is on track with the 20 million embedded PHR's and let us not forget Celgene which can come thru any day with a multi-million payout, Walgreens of course, Australia, the really BIG boy China and a multitude of signed patent agreements (future agreements coming) already in place that MMRF will profit from. I refuse to watch the caboose pulling away and wonder why I sold any of my shares. I accept the ups and downs of the market but this PPS will ramp up quicky with the "irons in the fire" that MMRF has worked so hard to acquire..JMO...Tiffer
