how to disable activation on email?

my friend is having hard time in registering in my forum coz of activating account from email. how can i disable it? si when they register, they dont need to activate it?

You have to activate it somehow. You can do it yourself by admin panel.

Admin Panel // User & Groups // inactive list

To change to way you activate accounts

User & Groups // User Option // Who can activate accounts.

is this correct too:

Admin Panel > User Tab > User Option > New accounts activation : "Automatic"? thats what i did

Yes thats correct.

thank you,
