It is time to we are update again to things we don't know before, this is 21st century and we all need to be updated with how things goes......for example, do you know that if you type "Q*@" in a social media group you might belongs to, it automatically brings out the name and number of every one in that group. Watch out for what computer age is coming to in the next few year........but make sure you are a literate and not an illiterate.
