So that the same question doesn't have to get answered again... and again... and again...
I get about 25 messages every day, which I try to answer on a daily basis. If I could cut that number down, that time could be spent improving other aspects of NS.
OP originally messaged me asking about 4-5 different questions on the topic. I did my best to answer what I knew, but I'm far from a tech expert, so I asked him to create a thread in SD so that Doug & Paul could come in and drop their knowledge.
Hope that explains things! Cheers.
