Hi Tim
I looked at the topic you mention and it would appear that someone sent you a personal message that you may not have been able to reply to.
You need a post count of 2 or 3 to use the system which you now have.
So you can now reply to the personal message, but it would also be good if you can reply on the topic here
http://www.rootschat.com/forum/index.php?topic=615960.0I know it's tricky finding your way around when you're a new poster, so check your emails for notification that a reply has been received, your profile is set that you only receive the notification of a first reply so you may miss them, but when you log in to Rootschat, there is a button at the top of the screen [New Replies], if you click on that you should also see the topic listed.
