I have yet to put an order in. However, from your post (Adam's) it would appear that the ISX trading number would not be required to place a trade. Warka/ISX sent me an email with the number so I'm assuming that is there way of telling me that I'm free to start placing trades. On a side note it took about a month for them to provide me this information after they received my info packet. I plan on looking into stocks to purchase this weekend.
thanks,
