Many editors are happy to share advice about starting out. Louise has written out advice on how to ask a busy freelancer for advice. It’s very good, so I want you to go read it. I’m creating this post just to make sure that you will read it.
Go. Read it.
Also, read every other post in this category. I created them to answer the FAQ. Following Louise’s advice, you’d better only contact me with follow-up questions; I’ve got a paying deadline to meet.
