I think i got it - add the line to the blog?.php file:

$login_required = true;

Seems to be working

It's possible to access the blog from index.php?blog=33
You should also disable sitemap and rss feeds.

Thanks for the info!

Could I use the $login_required = true; in the index.php file?

Also it seems members are unable to upload images, would like to have a blog for family photos.

Thanks!

I think I got it, change the additional permissions in the group to allow upload files.

not easy - but seems to work.

Thanks.

Seems like I missed your reply... yeah you can put $login_required = true; into index.php
