Thanks for the very informative post, Don. I have been on here about 8 hours now and have placed my order with cignot to begin my journey (510). When I registered here this morning, I knew nothing about ecigs. Now, 8 hours later, I feel like I have learned so much, lol! That is one awesome job you have done there and it was just exactly what I needed and wanted to find. Job well done, and again, thank you so much! Happy vaping!
