I know of the articles but I always learned much more when looking at the code than viewing articles. I also wonder if there are paid staff here making articles. There are far more programming techniques for vbulletin 3 in the vb3 mods than in the vb 3 article section.
The only Paid Staff here is Marco but I don't think he is paid to write articles. I know he has got a couple of articles written though. He just hasn't moved them into the Articles forum yet.
