Is it just that you can't see your reply after you enter it? or can you not hit "submit?" Discussions work kind of funny on this forum. Sometimes, you post a reply, and you can't see it for 30 minutes or more, but then, it just suddenly shows up. It used to frustrate me and I would post several comments, only to see all of them show up after some period of time. You just have to be patient. It's just a weakness in that forum, I think.
