With some enhancements to the site and on popular demand we have enabled to option to register using an address from the Yahoo domain.
We hope spammers will stay away. But if another spammer registers with a Yahoo e-mail address, and Yahoo again refuses to cooperate in banning such users, we have no other option then to man Yahoo from our system. Only place to complain then is Yahoo.

Because the PM system was still being misused by spammers, hoping to stay under our radar, we decided to disable the PM system for "new" users.
With new users we mean people who are not or very little active on our site. And with being active we do not mean downloading as much as possible. After you have been active according to our policy, you will notice that the PM system will become available to you.
