You need to know some background.
Today is 2/20/2009, Nine days ago I purchased this subscription.
At that time I was ranked 112 and 256 for two of my core keywords. Today I am ranked #3 and #16 respectively on Google.
It is a known fact that Google loves Wordpress and Joomla. Putting them together ... Brilliant!
WARNING: What else you must know is to read the simple directions. The one issue I had with installation was from me 'assuming' and making a simple mistake. One call to support and done.
This is a straight forward installation and works out of the box. Do your self a favor and grab the additional modules and plugins. They will make your site stronger for SEO and functionality.
The support has been 5 out of 5 every time I have had a question. Since installation I have had the pleasure of customizing a new theme and Rafael was excellent at helping me understand what I needed to do.
They have released several new modules and converted many WP Plugins since I made my purchase and I have to say that everything I needed to run a blog within my site is there.
Make sure you get some SEO module running, I use sh404sef and they have the plugin to go with it. So we have nice META and Title information right form the Posts.
Bottom line. If you want a fast deployment, scalable blog .. buy this.
