Wow, really guys? $150. We have a multisite set up due to conflicts with plugins running on the same site, so we created multisite only out of necessity. This looks like a great plugin, so we installed only to find a bit of a bait and switch. The plugin installs fine, activates no problem, but then when you try to find the settings page, it's buried in the Super Admin area with a note to drop $150 in your tank.
I'm not cheap, I buy plugins every day but $150 is way off the mark. That's Gravity Forms territory...you need a database with shortcodes, CSS and major customer service to justify $150. This plugin is worth $25 tops. :S
