I've had a look through your 21 writeups. I had no trouble understanding any of them (which is more than can be said when I look back over my own!).

You have asked very interesting questions which in turn provoked replies that I found enjoyable and very useful. Thank you for that. You even managed to spark a quite undignified spat between a couple of monastary heavyweights. That, xiaoyafeng, I would regard as a result! :-)

Even when BerntB had a slight problem with your English he gave you the benefit of the doubt. I'm sure all monks will.

It's clear from your questions that you put in a lot of work: reading the docs, trying out code. As you have noticed, if you do that many monks will be only too willing to lend a hand.

On a stylistic note I would say that your code is not garbage and your questions are neither foolish, childish nor stupid. Don't apologise or put yourself down.

As you've asked, I'm sure you'll get lots of help with your grammar. I only hope you don't end up regretting it! :-)

Welcome aboard, xiaoyafeng! I look forward to your questions!

Update:

<cough>
Fixed eight errors in the grammar/spelling/puctuation. Many thanks to jdporter for pointing them out.

There must be some sort of lesson here but I can't quite figure out what it is. :-)
