Organic Groups rules

Hi all...

I'm still slogging through setting up Organic Groups for the Alumni site I'm working on, and I'm getting stuck on an element that I'm pretty sure should be fairly straight-forward.

The client wants the Alumni section of the site to act like a site within a site... in that, when to go to that section from the main navigation, you would be presented with a separate tabbed-navigation at the top of the main-content column in the middle of the page.

I suspect that this is something that I would accomplish with Views, but I'm not sure where to start. Suggestions, anyone?

I all,

I'm using Rules, Organic Groups, Organic Groups User Roles (OGUR) and Workflow modules in my web site:
- There are group Moderators and Editors
- Moderators and Editors belonging to a certain Group cannot interact with other Groups Moderators and Editors

I have a lot of rules associated with "Workflow state has changed" event: all works fine, except for a particular rule that doesn't work in the right way: I need that when a Editor put his article in "to approve" workflow state, the system send an email to his moderator.
