Hi WPMU Support,
Going through your beginners manual and it states that you use and recommend Psek, which is fine, you are recommending what you actually use.
On your website you recommend WP Engines and CoolHandle, guessing you do not use this hosting providers. Can I ask:
1) Why the discrepancy between manual and website for hosting recommendations?
2) Do you actually use CoolHandle?
3) Do you actually use WP Engines?
Can I suggest that you open up a comments section for customers to feedback openly on your forum as to the service they receive from your recommended hosting providers.
Lastly, the obvious question, who do you actually recommend from the three?
