HI!

It is a very emotional and thrilling moment for me to see the revival of the project. There are just too many small episodes and incidents associated with the project during its development some 15 years+ in history.I still cannot forget the big TARBOOZ that LRL would bring for refreshment, Hi! Hi!.

Along the way many mods were worked upon that we could not make it public due to various limitations and commitments. ATS1 in itself is an excellent project. I suggest just go ahead with it.

Rest assured I will be posting many mods from my wizard cap , just to make it better.
