Thank you for a great application. Currently I am tracking more than 10 related site under one piwik server. Everything works fine for individual site reports.
However, I have one problem: If I want to view report for a combination of websites says (e.g: currently track 12 sites and viewing report for each site individually. Now want to view report for 10 site in combination.)
If possible should I write a plugins? or just modify the source directly? Please give me advice on the right track.
Thanks you so much
