I am not sure if this is the correct place to post this. If it isn't please
suggest an alternate.

I am soon to migrate to GW2012. I was wondering if there has been any
changes to how shared and published calendars handle Coloured categories.

I would like to know that if I set category colours in a master calendar
that I then share whether the other users will see the same colours? I can't
do that in GW8.

In addition, If I were to publish my master calendar to a web page does it
maintain those colours?

If I have several calendars that I wish to publish can they be overlayed so
that the web page shows all of them on one page? If so how?

Is there a simple way of restricting who sees a published calendar or parts
of it based on eDir group?
