WordPress MU

I'm using MU because I have multiple blogs. I had no intention of anyone else using my MU install for their blogs nor is it advertized as a public blogging site. Anyway, seems some robot has picked it up and someone has set up a blog.

What do I need to do to make my install private?

Thank you.

Add the following snip of code, or something similar to the top of wp-signup.php:

if( is_site_admin() == false ) {
    die( __('<p>You do not have permission to signup for a blog.</p>') );
}

renaming the signup file may be helpful as well so folks don't hit it trying to find a way in.

And setting the "only allow from" in the site admin options too.

Which, actually, would eliminate the need for the above.

They could try, but they would fail.

Agreed on the trying but if the poster gets either spammers attracted to them or folks who don't realize that's it's a closed system, they're going to keep on trying over and over again.

Eh, we could fail 'em twice though. just because we can. :D

Hmmm, drop them into the htaccess file if they fail twice. Maybe they'll take the hint...

Thanks. I'll try various. See what works.

Also, what do I about the blogger who has set up shop on my site ... just delete?..

Yep. If you're feeling nice, you could email then and say why, possibly direct them to another wmpu site.
