You can't access chat and your posts are going into moderation until staff can view them to determine whether they are suitable for public viewing.
If they have not been approved then it's because you are posting something that is not allowed on the forum.
No specifics will be discussed in this thread or anywhere else on the forum. If you want to know why your account has been restricted and the conditions of the restrictions then please write a Letter to Admin and they will let you know what is going on.
Also, please keep in mind that your posts can only be approved (or deleted) whilst staff are online. There's no point posting multiple times if there's no one around to look at them. It's just the way it is and we try our best to get to these sorts of things as soon as we can.
