Do I have to Pay?

Once you decided to directly communicate with members,  other than the standard system messages, you have to upgrade to Premium membership.  

Premium membership is a paid service and you have to pay according the current charges.  If you are a Premium member you will be able to make direct contact with profiles that respond with you.  It also means that all members who wish to contact you could do so.

With Standard membership, you can not exchange any direct contact information such as your e-mail, postal address or telephone numbers.
