I only know what I've learned by playing with programs until I can get something to work. Often I've had to take long and hard roads to get to where I want to go. While I've learned a lot by this method I've decided I can learn more by just asking someone who knows more than me and adding their solutions to my bag of tricks. I have received nothing but timely and excellent answers here on EE and hope to remain a member for a long time and maybe learn enough to have something to add myself!
