Just using this user's talk page for example, as he joined today, I edited the welcome message but it still displays the default "none of the admins are active" message. How can I change this, if possible, without editing the user's talk page and changing it directly (because I'm not gonna edit each user's talk page everytime they join the wiki, I want it to be an automatic process)?
