After installing your software I noticed your software 'reaching out' and 'file' a google adsense subscription with a key that I do not recognize.
I also noticed my statrix module coming temporarily to a grinding halt.
I checked your site to find out how your software 'manages' newsletters, but could not find anything.
As a result I have disabled your plugin until I can get this sorted out.
I would greatly appreciate it, if you could help explaining what happened.
