G is on my site 24/7. Although I've put in loads of robot.txt entries to stop it crawling things like profiles etc, I'm wondering what other people's Google log looks like.... I just checked mine and its got odd entries like the ones below:

Query string
&cmd=sendentry&eid=48&st=
&cmd=printentry&eid=62

why is it doing this?

Googlebot is like an annoying person... that clicks every link of a site. In 2.1, that would be on the Options Menu (at the top of the topic), Print this topic.
It does everything.

These are Blog cmd's

So it is 'clicking' on 'email this entry' and 'print this entry'.
