good PlugIn, fast support

I am pretty new to WordPress and looked for a good Plugin to integrate Chimp. After trying out some I found Easy Forms for MailChimp, which did not look interesting first: I am a bit fed up with plugins that are free, but you need some costly additional stuff to let it work fine or they spam all of your backend full with “get pro” messages. And the discription sounded like exactly that.
Well, it is free, 2 other plug ins I tried weren´t very useful, so I gave it a try. And well, I was blown away. It looks pretty awsome, is easy to use, very well documented and does allmost more than the discription tells you. I set up the things I wantet, put up the widget and activated the “integrate with comment”-option and everything worked fine and fast. After that I had a little trouble with integrating the plug in even further into wordpress, (but this was my foult, not the plug ins´). So I asked the support and boy the answer came 1 minute later.
All in all: When you use MailChimp and change to WordPress with your website, this is what you need.
