Maybe this is not the best place to mention it, but I cannot find a better one.
The Silver area aricle "Get from gold to platinum with multitabling" is not too up-to-date, I think. (url: http://www.pokerstrategy.org.uk/en/strategy/133/ )
There are two link in the text, neighter of them works. 
All in all the text is good, but I think it needs a review.
