That could be true, but doing a search (or asking a question of a mailing list) then getting an answer that then has to be resolved by doing a further search is a step too far for me. And removing the numbers still leaves a list where most of the questions begin with "How do".
IMHO the numbers are more useful in the list than they are in the articles themselves. Although, having put them back in I see that the numbers don't imply any order to the actual FAQs. Breaking up this list into different categories might be useful, but I'm not sure how to achieve that with this wiki system.
