Actually, it's kind of funny to see this kind of response on this list. 
Most of the time it's much more high brow. We don't often get this more 
simple "how do I code xxx" kind of thread.

Yesterday I was reading about the latest open source forum where people 
were suggesting some things that M$ have done well vs things that OS 
developers do well and in many respects the amount of advice available 
on how to write various base functions is much more accessible for 
windows developers.

Although we have free code we don't always have accessible info on using 
it or understanding it.

It's a good thing this list has so many competent people reading it and 
responding quickly.

That's one thing we have over most of the M$ focused list and forums. 
Super fast response times to the common knowledge of our community.
