I can give you tha ability to attach files if you want. This is up to you. We don't allow this in public forums because of the risk of virus infection, etc. Right now, I have disabled this, but will enable it if you think it is a feature you want.
Rich and Don, I just enabled the ability to Attach Files so that you can test out this feature to see what you think. The only downside is that you can't collaborate on the files or documentation.. you may want to think about this but wanted to show you what it was like. You'll find the Attach Files link below the Message area.
