My Red Hat email address is linked to google services 
(mwringe at redhat.com). This is usually the one I use and prefer when 
work related. My gmail account is mwringe at gmail.com if for some strange 
reason my Red Hat one doesn't work.

This makes it  simple for them to do very simple layouts, but it becomes impossible to do anything outside of what we have decided is a "good layout approach". And if we want to add in new features later (like responsive layouts) it becomes more and more complex to it in a simple drag and drop application.

Like what currently happens with portlets). If I want to use media queries, or float one container inside another, there should be a way that I can do that easily by accessing and modifying the source.

>>>> I think today the use case about responsive design configuration are not well known because we have a lack of feedback from customers:  from RedHat customers AND from eXo customers (those customers don't have the same needs as we know). eXo customers usually needs a simple and powerful visual experience, Red Hat customers prefers to edit XML (joking).

I will check with Benjamin Paillereau (perhaps he's reading that list too) on this item for the "Edit In Place" spec. I know he did some experiment recently with responsive design (http://blog.exoplatform.com/2013/01/24/juzu-day-3-the-coolness).

A few services have been developed for 3 years with goal to supplement it one day: NavigationService, DescriptionService and PageService . They have all been developed to fix a particular issue with DataStorage (performance or scalability). So a few things were still managed by the DataStorage : sites and layouts.

(consider a layout as an attachment of a navigation node or a page). Those services have been implemented with existing MOP and the goal was to make nearly all existing module pass. Only tests for dashboard do not pass because the dashboard impl is a hack that should not survive a long time (but persistence is very fine). The SiteService is quite trivial (pretty much like PageService). The LayoutService was also trivial because of the reuse of the Step 1 (which is a **big** win).
>>>>>>>>>>>>
>>>>>>>>>>>> Step3: all the NG services have been decoupled from MOP introducing an abstraction layer (SitePersistence for SiteService, PagePersistence for PageService, etc…). At this point the NG services tests are decoupled too.

The import code was decoupled from the NewPortalConfigListener (a component plugin of UserPortalConfigService). Then a new class wrapping this has been created for importing data.
