Well, don't get me wrong, please. I don't want to make any argue about
english grammar. and I don't have any capability for that.
It's simple. If someone says, there's no problem, then no problems.
And if there's something unclear, you guys could discuss about that. I
wish I could join in, though.
To be honest, I don't know the difference between "a" and "the" well.
Though I know the basic concept of course.
When I read the sentence, I thought the sentence might be not clear
and a writer might have made a small mistake. So I just asked you in
this mailing list to check that sentence again just in case.
