People may have seen the threads regarding this in the Portal's and on PUG recently.
We have started the build of this internally, and today we started looking at Skinning the various applications that are being tied together to look like the prototype (here).
We hope to be able to show off some screenshots of the skinned applications by the end of the week, once we have ironed out some minor creases. At this point, we then intend to invite our colleagues from around the business to sign up and have a play with it, and most importantly, try to break it before we let it loose on the customer base.
We're still aiming for 04/04/07 for a Beta launch.
What this has taught us (or me)
No two applications appear to share a common theming system. Drupal uses one type of skinning engine, SMF uses a different one, Wordpress uses a different one and a poll tool we looked at uses another one.
It would be so much more useful if every system used the same sort of skinning system, e.g Smarty because that would speed up the creation of the templates by our Design Team.
Thankfully, the integration of the systems has gone well in the main, but there's still more to be done.
