Yes welcome to LQ.
Be aware that you've resurrected a VERY old thread, last written in 2006. In fact the last post made by user johnpaulodonnell shows as 2012, so it may be likely that they are no longer paying attention to the forum, nor that particular thread. You can click on the hyperlink for a user's name to see posts made by them, this will give you an idea whether or not the person would even be available anymore. Further, when you went to reply to that thread, LQ should have warned you that the thread was last posted too in excess of 6 months or longer. It's worth considering when those warnings come up.
If you have particular questions, I suggest that you choose to create a new thread.
I do understand that likely you did the suggested thing and searched for similar threads or ones containing the concepts you were interested in. But in this particular case, the thread subject is so old that it's likely not worth attempting to raise it up again and instead just create a new question.
