Hi Oliver,
1. what do you mean with *mytalk* ? is it the talk page of the logged in user ? (which is
also a user_talk therefore and doesn't need to be considered appart) or is it simply
the link at the top of the screen (with "username My talk My preferences My
watchlist My contributions Log out") ?
2. do you want to completely *remove* the user_talk pages (the User talk namespace) so
no-one can even *click-read-edit* it or do you simply need to disable editing on these
pages ?
