As I close in on 500 published posts, it can sometimes be tough to find what you’re looking for if you have a specific question.  You can use the search box, or scroll through the index, but there are A LOT of results to look through.  I have compiled some of the most frequently asked questions here.  If there’s another question that needs to be added, just leave me a comment.
