boyle534, I see where you asked direction on how to make a new thread, and successfully did that.....congratulations. You did what many new members 1st do here, and put that thread under Forum Admin and Annoucements. I moved that to the the General Tech and Repair, where it is probably better suited. Not a problem.
To start a new thread, 1st open up the forum that you want it in, then do the click the new thread button and do just like you did this time.
You can practice this by introducing yourself in the Welcome Mat if you like.
BTW, I am not sure what you are talking about with the flexible duct either.......if you can post a picture that would be great. If you have trouble doing that, then PM me and I will help.
