Could someone explain to me how exactly this particular setting works (default is Admin):
"User groups above this can toggle the Tweet/Don't Tweet option, but not see other custom tweet options."
I've been clicking it back and forth and do not see any difference excepf for this text when I switch berween adin and editor: "Access to customizing WP to Twitter values is not allowed for your user role." However all other option tips for post are there (at least displayed, is it that they won't work witch such settings?)
Does it work in connection with two other group settings (i.e. I can select two different groups and block one: e.g. allow lowest group contributors for twitter info, authors for custom info but exclude editors from adding custom info?)
