Your next step is to upgrade to family member. It's free to upgrade. Then you can start adding your family branches and digging into the research. Once you have a few profiles added, come back here to the forum if you have any questions.
You might want to check out the project list. Projects are a great way to learn more, discover new resources and collaborate with other members. The project list can be found under the Find drop down menu. There's a Native American project, for example.
Good luck with your research and enjoy your journey into the past.
