Upfront in general is fantastic.
However, I have concerns with UX after a Multisite website is created using the new upfront themes.
The user has no idea that they have to login and then click the upfront button in the wp admin bar.
I will try to hack together a popup page, that encourages them to login, then encourages them to click the upfront button if they want to start editing their site.
Also a quick how to faq will be embedded in the popup.
Will this be integrated into upfront core?
It seems like it should be.
