It's been a long time since I was new here, but as I recall, there's a probationary period, during which your posting privileges are somewhat curtailed. I forget, but I'm sure it doesn't last that long.
As for contacting a moderator, you could find any thread related to forum business and pose your question to the Admin Moderator. Remember to delete the name of whatever poster is in the 'To' field, and insert Admin Moderator there. That ought'a do it.
Ok thanks.
