just reread the rules at the top of the page, and they seem pretty simple in number, just not too precise about what constitutes " commercial". I suppose those that those whom have gotten warnings understand better where the lines are drawn, but say for instance, if someone links to their website or blog to direct attention to a posting or page describing the method or technique being discussed in the thread, Is this considered a violation ?
There is a difference between sharing info, and direct endorsements of products or services.
Not trying to be argumentative here, just saying that the average poster might be a little under informed if the policy is very explicit. The policy seems to be very important to the sponsors (understandably so), and I presume most forumites do appreciate having that sponsorship.
