No Tinman, You are not being silenced. You can try a couple of things. Delete your browser cache/history, and cookies.
*Log out and log back in.
*Depending on the browser you're using you may have to login more than once to be successful.
*Move around on the site a little from forum to forum always checking your status on the upper right just below the MS Logo bar.
*If you see "Welcome Timman [Log out]" after going through all that you should be able to post.
If not let Nathan, the webmaster know by sending him a PM. Maybe he can discover what the trouble is.
