I know I am a new member but this is not spam.
I have started a group, for this same reason, its a hush hush operation right now, and I'm working on finishing the interface in joomla, for a site like this but by request only.
If interested PM me your request to be added to my confirmation list.
you will not be spammed and will only be contacted once with the details of the site, once published late this week.
