Another question: Is anyone using jetpack? How is it performing with sys website?
I recommend Jetpack and use it for stats, contact form, sharing buttons and it can be useful for custom CSS editing as well. Because it's provided by the Wordpress crew all of the plugins are fairly up to date and actively worked on by knowledgeable developers which is nice.
There are a few tutorials that include it here:
