This is exactly what we need, but after two days of configuration testing without success, I have given up using this on a subsite on our multisite installation.
I should have asked about multisite compatibility beforehand, but I just wanted it to work sooooooooo much. :)
After configuration and when a user clicks the Create My Page link, the popup form opens but it will not display additional fields added in the admin area and it always returns an error if I try to save it as is.
Any suggestions appreciated.
