Hi, many thanks. I admit I had suspected that indeed. So, I'd have a couple of questions more, please. 1) Does the caching simply imply a delay in the dynamical effects, or rather a chaotic behaviour (for instance, do the dynamic effects depend on the number of users that contact wikipedia on a given day, and so on)? 2) How can I use an "autonomous" bot? Thank you very much. Claudi --------------------------------- Ne gardez plus qu'une seule adresse mail ! Copiez vos mails vers Yahoo! Mail
