I understand your confusion! It has been difficult for me to navigate around the threads, and to figure out which response applies to "what." And, because of this, I've had my share of misapplied responses a time or two or ten. ;)
I say to you, "Jump on in! We learn best by trial and error anyway!"
Isn't this just the MOST fascinating place?!?!?
Welcome, blueeyez ... make yourself at home, ask questions, relish in the responses, take the time you need to absorb everything, and come back for more when you're ready for yet another mind-blowing (at times, slippery) experience!
