Are you SMART online? - Langle land - An e-Safe place to be!:
"Have you ever got an email, text or other things like that from people you don’t know? If you have, did you open it? And if you haven’t never open things from people you don’t know even if you are anxious to or really want to badly still… DON’T!
Because there might be an attachment with a virus on. If you replied to someone you didn’t know it would tell them what your email is to. Help us put a stop to cyber bullying and when you get an email from someone you don’t know:
* Block them.* Tell a trusted adult.* Delete it.* Next time try to be safer online."
