I purchased the component and had a few problems with the install, but Flavio and Romano stepped me through those *minor* problems with ease and aplomb.
They are new, but growing. I've received 3 updates since my purchase a week ago.
Folks, ohanah is hot... the next big thing for Joomla, right up there with JomSocial, OSE & RocketTheme. I'd give it 6 stars if I could. :)
