You are right. I appreciate your comments and thank you.

What annoyed us was the fact we didn't know how the merge would take place.
No nacks can mean no interests and does not mean the ack.
Coding issues/problems can be corrected, but we didn't know how to react with
different way of thinking and concepts. We were at a loss rather than
being frustrated.
BUT I know every those things can't be an excuse. I feel sorry for our
last posting. I apology you all and promise we will never do that.
(I don't mean we will stop submitting)

Yes, it was ... really surprising. (I was even scared)

It's a great pleasure to receive comments from people.

I couldn't agree with you more. I'll never quote that. :)

We started following the thread and found it's very close to
our case. We will watch and join the discussion.

Thank you. (T_T) (crying)

I wish I could revoke the above statement...
