flymar, thank you for your insight.  I bought some of the SNXXF and SDXXF warrants back in mid-2011 based on a recommendation from (Dudley Baker) and they have been very good.  I plan to hold onto them for a while.  I have read that normally one should not hold onto the warrants past one year prior to expiration so for the 2014 warrants, I plan to keep until next summer (if the fundamentals/technicals of the company are strong, of course as we all expect them to be).
