keep a positive digital footprint
Once you post something online it is there forever, you will never be able to take it off.
You won't be able to get into the collage of your chose if they find out that you've posted something inappropriate online.
You always want to be careful online. Ask a parent to sit with you at the computer to ensure safety. If a random person is somehow conected to you and texting you stop contact right away. Also keep your computer up-to-date to avoid problems with a hacker and a 21 character password is suggested.
