New To P99 Site - How do I Private Message?

[Doraexplorer]

Hello all; I am a EQ Vet from live servers. I've been off EQ for a long time. I'm looking to join P99 soon. I figured I would join this forum site, to help get ready and get to know about the community and server before I play. I'm waiting for my nice new computer.
If I had a private message to send to an Admin of this forum site. Or if I had a Private Message for a GM or a P99 staff member , how do I send a Private Message?
It says I'm not authorized for Private Message.
I've been on other forums over the years, and at times I want to send a helpful message to an Admin , or a question that I don't want viewed by all.
Sometimes certain things may be private when I don't want certain members to be able to view.
My messages would only be helpful to the staff and nothing inappropriate.
I just haven't been able to figure out how to send a private message and how do I find out who P99 staff members are. I figured certain staff members were assigned to handle personal messages from the community.
Any help is appreciated.
