Hi Erin - I'm new to this whole thing also! Its nice to hear that not everyone is up to date!I've only had my computer for 1 week and I have absolutely no idea what I'm even doing yet, so bear with me. You pose an excellent question and yes I am very concerned with the possible long-term effects. I hope someone else has maybe done their homework and we can both learn something. Let us know if you hear anything other than here.
