i'll point the admin toward this
PM's are now called conversations, click anyones name under their avatar, or in the members list, and a box will open, you should see the "start a conversation" option ?
To combat spammers as well as to promote public forum interactions, there are now a few small requirements to be able to hold individual conversations with other members. All you need is to be a members for at least two days, make three separate posts and have three likes. See the following link for more information: http://www.blasterforum.com/threads/membership-types.59230/
You can always comment in the thread of the person that you want to chat with and ask them to start a conversation with you in which you will then be able to directly reply to without even meeting the above requirements.
