Not sure... do we have to LOGIN ... no we don't?

Hi Support Team,

please advice us what's the right thing to do,

We installed Google Analytics+ at NETWORK Admin level and activated it there. Connection to google works and statistic is displayed.

Now, in addition to that is it correct to activate it on each sub sites too? If so, that requests on each site to gain a unique access code.

We wish to activate on every single site in order to see the statistic on each site just for that specific site but we are not sure how might this effect the Network Level, where we would need to have the statistic as summary across entire network?

Thanks in advance.
Regards,
Prinz
