Thanks for the quick replies and detailed information. I'm quite surprised that the Pro subscription at $99 per month only includes one user. For an application that costs $1,200 per year to use, allowing one user seems pretty weak.
In comparing pricing across the landscape of SaaS webapps it's a unique case.
I'm also a bit surprised that other users are willing to signup for seperate accounts, in my opinion, the pressure should be on SEOMoz to better serve users but allowing for multiple users per Pro account, at $99 a month at least three users seems more than fair.
