It is currently nowhere documented what rights non-editing teachers will have. I think it is important to know. Does anybody know? Especially with respect to groups? Or does anyone have an opinion on what the rules should be?
I think there is currently some inconsistency between modules. For example I think the rules followed by the wiki module, see http://moodle.org/mod/forum/discuss.php?d=7437#35116, are different from those followed by the assignment or forum modules.
