enable pm by default?
 

for some reason my PM feature is not automatically checked when someone registeres....how do i fix this?

some reasons: (If users cant send PM even if they choose to receive)
1- You have edited the new registration template and accidently changed the relevant PM field HTML code

2- You applied a hack which edited register.php and it caused it.

3- The usergroup new users are assigned are not granted PM feature.

If they can send pm if they choose to receive but by default "not receive" is checked in the registration form then focus on 1.
