Hi,
I've created a new group type called 'newsletter', and I want to add everyone (about 2000 people) to this list (then i'll manually remove the few that don't want to receive newsletters).

Is there an easy way of doing this? I cant seem to see how without going through each person individually...

You could write a small function within SS that copies the users over and then visit the function's address in the browser to trigger it.

ok, if there is no function within the CMS, i'll probably do it by exporting a CSV file of all the members, opening in excel, removing all the data but the ID, and then importing again into Group_Member table..

Hey - no need for the export you can just do a little function like this:

function MoveGroups(){
	$oldGroupID = "1";
	$newGroupID = "2";
	
	$oldGroup = DataObject::get_one('Group', "ID = $oldGroupID");
	$newGroup = DataObject::get_one('Group', "ID = $newGroupID");
	
	foreach ($oldGroup->Members() as $member) {
		$member->Groups()->add($newGroup);
	}
	
	Director::redirect($this->link());
}

Then if you set the IDs to be the correct groups and run the function it'll move them over. I haven't actually tested that code so you may need to play with it a lil to get it to work.
