I too have a bone to pick with EK about their errata. For one thing, the 6th and 7th edition books are the same thing with some typos removed, old typos overlooked, and new typos added (none of which are seriously problematic).
The "paid forum" which I bought into for 3 months access doesn't even contain but 1-2 errors per book and when you challenge a question some moderator comes back and insists the student is wrong, not the book.
The 1001 books are wrought with errors, inconsistencies and vague/counterintuitive explanations (particularly the biology one which I completed 2 times cover to cover) yet theres no real easy way to view the errors (not that they would admit to them) because the forum is haphazardly arranged.
All in all, I suggest you save your money and don't buy the forum access--- your not missing much because theres hardly anything there. Of course, I don't blame EK for having errors, these things happen... but the errata forum is just a waste of time/money.
