I have looked at your problem and have found nothing wrong. It may say that the forum is locked but that does not mean it is. You may still click on the "locked" button and post. It is difficult to know what you can get into or not and if you have any doubts either:
A) try clicking on the button,
B) send me a private message,
C) GAS IT OUT!!!
If these suggestions don't help, send me a message anyway. I will look father in and make some new changes if needed.
