You don't need to accept the quests, Honorbuddy does. Go to this forum, and select a profile that is clearly marked 'questing' and matches your race/faction/starting area, etc. Then set the Honorbuddy bot to 'Questing - Beta', and hit the "Start" button.
If you need help understanding more about Honorbuddy in general, see the Wiki--there is tons of information there. If you need some help understanding Honorbuddy settings, these pages should get you started:
