First things first: we suggest you change your password to something you'll remember. You can always reset it if you forget. We also suggest you update your details with gender, job, Country and other details about yourself.
We take your privacy very seriously.
By default your gender is displayed here on your "My Page". If you wish to make this information non-public, simply access your privacy settings. You will notice that you have an option to hide "Age", but age is always hidden on this network.
