Are you looking for just the technical parts or use cases for specific scenarios?

Mainly technical I think.
I'm trying to set OG up as a major part of my Church's website - but want to make sure it's easy to use, simple, and looking good/consistent

I really want to be able to set up panels on the group pages, and have been looking at the OG Blueprints module, however cannot make it work for all my groups.
If anyone has had expereicnce in this, or another waty of themeing groups pages, some help, or steps to do this would be great!

yeh, i 2nd sejtraav's request for some more involved OG tutorials, though i'd like a non-technical overview first, if its possible

eg: if you outlined 5-6 reasonably complex ways Organic groups are used, which between them covered most of the associated modules & the common use-cases, that would really help

(that approach always works best for me)

The folks at Acquia just released Drupal Commons, a distribution/profile that gives you an immediate Organic Groups setup. While it isn't a tutorial, I'm finding it to be a way to get immersed in the world of OG very quickly and relatively painlessly.

If you're still wondering about OG this is definitely something to take a look at. The download is free and you can run it on a local stack if you wish. I had just started building a site for a local PC users' group when I saw Acquia's podcast and decided immediately that I was going to use Commons.

Hope this helps someone,
Curt
