Currently there appears to be no connection between licensing for SiteCatalyst itself and access the SiteCatalyst NetAverages tool via CS Live.
According to Adobe's CS Live FAQs:
but it seems this should be available if one is using SiteCatalyst. It seems logical to include this with SC, which is a much more expensive product.
Are there any plans to offer NetAverages with a SiteCatalyst license?
Or does our SiteCatalyst software provide this data somewhere and I haven't discovered yet?
