If Orbius is successful, users will belong to many groups and orbs. Notification will be a big issue. I strongly suggest an approach that combines all the notification settings in one view for all orbs and groups. This will make it more manageable.

Can you allow the Orb administrators to decide whether or not their Orb's Members can make their page private? For my community in particular, giving a member the option to keep their page "private" defeats the overall purpose. It's not a "content-sensitive" site so I see no reason to allow private pages. (And I think in some cases, members are simply unsure and so check "private" because they're given the option, not necessarily because they want their page private)

Members would decide if they want to publish their Birthday(Month/day) to the community and displayed in a calendar form.

I'm using Orbius for a private Team Collaboration project and its fantastic! You should create a simple template for this.

Frequently I wish I could add a list of items to my site with multiple columns/fields of info for each item.

The main horizontal menu bar could be improved by displaying a drop-down with the most commonly used choices visible. This would allow a user to add a post to a blog, or add an event to a calendar directly from anywhere in the Orb.

I am a member of 10 communities with different connected member lists in each community. How come I can see everyone I am connected with? Also, relating to an earlier post, I'd love to be able to invite my connected members to my other communities.

You need to add a way to invite existing Orbius members to a new group. My nephew joined a community I set up and I wanted to invite him to the Orbius Support Community because he develops websites and wants to become familiar with Orbius. The fact that I had to re-email him was a pain. Facebook thrives because people can create groups and invite facebook members easily. Orbius needs to do the same to grow.

Since many organizations have groups with fixed members, it would be helpful for an administrator to be able set up the groups by assigning members rather than having to send invitations individually to each person. In our case we probably will have a minimum of 10 - 12 organizational groups with a total of 60 plus members. It is a lot of work to have to invite each one individually.

I'm not sure if I'm the only one, but the pop-up menus are confusing in that its not clear the the first menu item is active. I thought that was just the title of the menu.
