WordPress MU

I'd like the option for "users must be registered and logged in to comment" on by default for new blogs. Is this possible?

The default value of this is set in the "populate_options()" function found in the file upgrade_schema.php. This function is called when a new blog is created to set its default values.

There is a line that says...


add_option('comment_registration', 0);


Change the 0 to 1, and it should do the trick. Blogs that were previously created will not be effected. If you want to change those you could do some direct SQL manipulation of each blogs something like this....


UPDATE wp_2_options w SET option_value = 1 WHERE option_name = 'comment_registration';


Assuming you want to change blog_id 2 and your table prefix is "wp_".

Good Luck.

btw, if you want to do this without making direct core changes, you can theoretically implement a new version of wp_install() and wp_install_defaults() which are both pluggable.

Thanks very much for your help :)
