Okay. The data from the Wordpress Users must be minimal like that:
- phpinfo about the version
and
- which pluigns does a wp install running (active or deactivated?)
This will give you an overview about the wp users with the plugins and the php-version. This is incredible.
I really heard this the first time of my wp life.

In Germany it is illegal to send data to another non-german driven host if the complete IP is included. We must mask the IP, if we do that. For example: 123.123.xxx.

So. Where can i get an concrete information about the hole data, which is sending to wp.org. @jeff chandler: Your article is not clear enough.

p.s. to yoast: Your automatically activated onpage.org "feature" is sending data to onpage.org, too?
Which concrete data? Isn't this illegal in german, too?
