All, as I am very new to the hobby, please forgive my ignorance, but what are the safety measures that both providers and hobbiests put in place to prevent spread of anything?  Thanks in advance for your responses!

read the Self Help section (link bythe life saver).  Then read back on this board several pages.  Once you have done so, we'll be able to have a conversation where you have some idea of the subject.  Then bring any questions back to this board & we'll be glad to answer them.
