I'm changing the group settings so that only staff members can ping to the Site Update group.

Huh - that's strange. The options are specifically only admins can post (and have been since I made the group). I'll take a look at it, though!

Try now. I think it was an issue of case sensitivity.

I tried to push out a few more changes last night. It does not seem to be working still for whatever reason.... Will continue to look into this

Is this still an ongoing issue for you guys or has this been resolved?

Ok I will go ahead and lock this up. If anyone else is still having issues please let me know and I can unlock this.
