I never made that a configurable option, but you can fix it in the code, if you want to.  Find this line in subscriptions.module:

return array(array('title' => t('Subscription settings'), 'data' => form_checkbox(t('Automatically subscribe to threads in which you post.'), 'subscriptions_auto', 1, isset($edit->subscriptions_auto) ? $edit->subscriptions_auto : $user->subscriptions_auto, t('Checking this box allows you to be automatically subscribe to any thread you create or post a comment to.'))));

Look at this section:
isset($edit->subscriptions_auto) ? $edit->subscriptions_auto : $user->subscriptions_auto

I think you can change ...

: $user->subscriptions_auto

to

: true

That's someone else's edit, so I'm not sure what "$user->subscriptions_auto" is supposed to offer, thut that whole block is the "checked: value of the checkbox.

I should probably add this as an option - I've had people ask about it before.

Hi,

Im using subscriptions module for 4.6

How do I make 'auto subscribe' feature default? I couldnt find a way
through settings.

If I have to do this in code, which table/column stores this information?

Thanks,
