Providing important information like Date Of Birth,Email IDs,Phone Numbers , Mailing Addresses to anyone is very risky these days.But these are the commonly asked info when you register for any service/account over web.If proper measures are not taken it will lead to spamming,Infromation theft,even financial loss etc.,I am herewith listing few points that one can keep in mind while providing these important information next time...
1]Do not register to each and every site you come across.Think how frequently you will use the information in this site.Are there any other sites that provide the same info without any regsitration.
2]Do not always provide all the requested information at the time of registration.
3]These days you have many email accounts with many service providers.So maintain different email accounts exclusively for different purposes.For example with your Yahoo account you can communicate with friends,With Rediff you can apply for jobs, with Hotmail or GMail you can maintain important information,etc etc.,
I maintain a Gmail account especially for all the shit registrations I do over web.Please maintain different passwords for these accounts.
4]Do not check the Remember me on this computer option unless you are the only one who access this computer
