I have mine set up to post as a new thread in a forum...but for what you want you might want to try it like this :
Thread ID: the id to the thread
Post ID: (leave blank) this will only post as a reply to a post and not as a new welcome to a thread which is what I assume you want....they are both very similar but you want to post as a new welcome post in a thread as they are coming in ...
