Re: [Server-devel] [Fwd: Turn Editing On missing and joining multiple courses]
Thanks Tabitha, I realise I should be clearer about what I am asking. I understand the Moodle context-based administration. It is rather the effects of multiple course membership on the presence service when split by course, which I am uncertain about. Let's say user A is a member of course 1 and course 3. User B is a user of course 2 and course 3. Does that mean that user B will be able to see all the members of course 1 as well as user A? I don't see evidence of that in our deployment but I am just checking in case this could cause issues with the presence service. We are using low-power (and low-RAM L) servers due to our dependence on solar power. So we need to make it work most efficiently and as I understand it, that is best achieved with small user groups segregated using the presence service. Regarding the other matter; logging on as Administrator is according to XS Techniques and Configuration a non standard task at your own risk. I am trying to use standard recommended procedures, which can be safely replicated by the local trainees, using the first XO registered - which is a partial administrator (it can create course creators, but cannot delete courses). If I create a course creator with that initial XO, they do not have turn editing on appearing which means that they cannot (for instance) create global links to public folders on the front page - even if they are Front Page course creators too. My question in regard to this issue is whether what I am observing is NOT what I should be seeing, and there is a problem with my system, or whether your inference is what I should be noting in that you have to actually log on as the site administrator to create a full replica of the first XO.
