Social Networks - Protect the confidentiality of your email account
Always be careful with sites that you join and how they use your email account. Also, avoid sharing it publicly as it could be potentially misused.
On social Web, beware of address book mining
QUOTE: When you join a new Web site, how often do you read the terms and conditions before you click the accept button? Most people probably answer never or rarely. And that’s understandable. Many just want to get on the site. Who wants read a document that goes on and on in language that only a lawyer could understand? That can be a big mistake. You never know what could be tucked in there. When you go to a new site, make sure you know what you are allowing them to do with your personal information.
