>it��is useful to write an answer to your problem on the mailing list: the��problem you met was or will be a problem for other, so it is a nice,
simple and effective way to contribute.Should one embrace the policy of each time one gets a question answered or a problem solved on the list, make a self answering post on Stack Overflow to render it readably available to others and also as a practical display of gratitude? If the question gets closed it won't be matter (or just a little)
Best,
