HOLY SHIT. I absolutely do not remember
writing all of that. I couldn't have been in a blackout at the time, so it's freaking me out seeing all of that.
But anyway, at least I don't have to write the answer to OP's question again since I just linked to everything you'd ever want to know about how I found the forum.
What a nice thread with the comprehensive answers from different members. Really has The Sceptical Chymist has said, there is no need for him to answer the OP again because everything is there, and anything we answer here has already been said in the link thread. If OP made a rigorous research he would have made comments over there. Though everyone has their own reasons of joining the forum, many are here to education, some are here to learn, some are here to advertise their products while some are here to participate on the campaigns.
