Thanks Mecha - I'm sure I speak for Raga too. Your comments are very appreciated. Awesome compliments! I am happy that you found it so entertaining and enjoyable; and for your girlfriend too - that's awesome to hear! My wife sure enjoyed it, and I wouldn't have felt good about it had it been something that didn't work for her. Fear not, we are working on the sequel and it's (finally) starting to come along smoothly and I have a feeling it will be even hotter; just by what I've seen so far!
