You should never type your address on your blog because people could come and steal your stuff and follow you to school. You will also have to keep your emails private to yourself because people will go onto your page and write bad stuff to people.
Don’t give anyone personal details because they could use that information. When you are creating a password you don’t put your pets name because they could know your pet.
If you are creating your own password you have to type letters and numbers and use at least characters.
