Hi IrishMe, Welcome to PC.
(Also welcome to kacey321 too!)
All new members undergo a moderation period, up to their 6th post, where they need to be approved by a moderator or administrator before they will appear on the forums. Unfortunately that means that if you've posted 6+ posts, but they're all in moderation, it still means you're a 0 posts overall.
After 6 posts (or whenever the forum software catches up which can take a few hours to a day) your posts will automatically appear on the forums and you won't be under moderation.
Unfortunately this is a necessary measure because some members or spambots come here and post things which aren't appropriate and it's easier to deal with when the problem is contained. I apologize for the inconvenience!
To access the chat room, you must also have at least 6 posts on the forums before you're able to enter chat and talk "real time" with other members - once again this is a security measure to protect members.
All this is also to say that we moderators and administrators are all volunteers and keep different hours on the forums, and we aren't always online to automatically approve posts. Generally speaking though, posts are approved within 24 hours. I hope this answers some of your questions, if you have any more please feel free to PM myself or another member of the Community Team.
