Well that IS a very wise choice young akaivan. Just know this: These predators don't try to be so bold as to ask you to meet them. No, they find out details about you, just little ones at first. Like what grade you're in, what music you like, etc. This would tell them approximately how old you are. Then they can probably know what sex you are. This can go on for weeks and then they know what city you are in, etc etc.
An FBI agent working undercover on a on-line chatroom, met a 14 yr old girl on-line. To make his point to her parents, he showed up at her house one day. From half a continent away!. He found out that much info from her by just pretending to be a 14 yr too. Where do you play baseball? Really I hate uniforms, I bet your uniform looks real gay!
Just be careful NOT to talk to strangers. Just because you are on-line at home doesn't mean you're perfectly safe.
Take care.
