Greetings Brittany, welcome to Steemit. Probably you have a lot of questions about it and the best way to get started is from reading the Official website FAQ: (https://steemit.com/faq.html).

Don't lie too much on the blog post because after 7 days it will locked up and there is no way to edit or delete it since this is a block chain blogging platform.

Have fun exploring and posting your experiences in Steemit. All the best!
