Many newcomers to this site have code that they entered into their notebooks using one of tje Mathematica palettes, e.g., Basic Math Assistant. They are delighted with mathematical look of their code, but when they copy such code from their notebook and paste into our editor, they often get a mess they don't know how to deal with. So they just leave the mess or they resort to making a PNG image of their code and posting that.

When they are chided by a community member for posting their code in a bad format, they are often given the advice to copy the code as plain text. My experience is that such advice is not optimal. What would constitute better advice?
