Disco Stu Got it right, Thats not what I want, I dont want these new members login until they have completed the registration process by clicking the link. and if they dont do so their account gets automatically deleted say..after 7 days. I have seen a lot of forums have this function.
setting the permissions to include "can't view posts" would be just ridiculous since they can just logout and view them as guests :P
Exactly. And since disallowing Guest viewing would be suicide (search engine spiders are Guests), there's really no way around it. Just prevent them from posting or editing their Member Profile or sending PMs until they are activated. And install that add-on I mentioned above to delete them after three warnings and 10 days. Letting them look won't harm your forum.
