Dating online has made it easy to connect with people you would not be able to meet under normal circumstances. The option to be in contact with somebody who might live far away seems great and it is, but you should be careful.
Many people dating online have had horrible experiences; do not let this happen to you. Your safety comes first.
Do not give out personal information when talking to somebody.
If you want to meet, meet in a place where the two of you are not alone, for example a public place.
Your profile is what people notice first when they judge you. Keep it respectful and clean.
