Enforcing rules feom wordpress admin

[Triggerhappyme]

Is there a way to enforce the rule from the wordpress admin area rather than the group admin. Or even set it so as long as the plugging is active the following is achieved without any backend settings.

What I would like to achieve is, that for every public group that gets created it is default that its necessary for any members must request to join.

I don't want the group admin to control this.

One work around would be to add the options to the group creation pages and set the radio button by default to "users need to send a request".

I could hide the rest with CSS.

Any advise?
