So, I'm putting the final touches on AtriumED (sic) with a couple new OpenAtrium features additions:
-Quizlet Vocabulary: https://github.com/markwk/atriumed_quizlet
-Group Video Chat: https://github.com/markwk/atrium_opentok (using OpenTok's free Video Chat API!)
I hope to have a distro to share within the next week or so...
I noticed that I probably needed some kind of assignment / submission system so tonight started working on getting a feature together: https://github.com/markwk/atriumed_assignment. It uses an assignment content type and a submission content type that is node_referenced via http://drupal.org/project/nodereference_url. It'll probably use something like views_attach for the assignment page.
ISSUE:
I want to limit non-admin in their creation of assignments and only allow members to create assignment submissions.
Is there a way to control this permission without a separate role assignments (i.e. manager)? Are there any other features already doing this?
And if you know, how might this node creation permission be controlled for just og group admin?
Thanks

Have you tried OG Role to
Have you tried OG Role to assign group specific additional roles to a user? Then you should be able to limit which roles can create the assignment (or potentially limit the number of assignments they can submit through node limiting modules)

~Cool Functioning Module~
~Cool Functioning Module~ I'll have to look at the code and see if I can steal just the lines of logic I need, because I'm not particularly interesting in adding more modules to an already module heavy site. If you are interested, check out the demo that went live yesterday: http://teachers.language-corner.org/demo !
nice looking demo!
I need to try out those features still that you posted above (on the list of things to do). Very nice looking reconfiguration of Open Atrium :) You had asked me about the Scheduling tool before and I recently posted about it (yesterday). I've repackaged the feature based on Kit and had it working in open atrium w/o much of an issue. Here's a post I did on it: http://elearning.psu.edu/elearning/creating-features-ecosystem-through-kit Has the repackaged feature attached at the bottom

Cool...
Yeah, I just updated the git repos so they should be working decently now.
The OpenTok stuff has a huge potential to providing a video chat or broadcast option. I've tested it to work with broadcasts out of 10+ and the OpenTok developers I chatted with said it can handle a couple thousand. I got group video chat to work with 4 folks (only tester available at that moment :-) I think it just needs a more live text chat option to complete it. Any thoughts on chat with Drupal?
The quizlet API is getting updated soon so I'll probably need to to update to allow more dynamic vocabulary within drupal. It's definitely a nice addition to the Drupal Edu ecosystem, I feel.
I'll take a look at the new version of scheduler with openatrium soon.
