iTunes U Apple Host Content HOW?
I'm completely lost - i dont upload to iTunes U very often. once a year, maybe. Previously I have done it all via https://sitemanager.itunes.apple.com/
this gives me one option to put stuff through iTunes U and that is to add podcasts = when i do that it will only offer me a chance to add a Feed URL
Sadly, the host server i used to do this with, no longer creates a feed for me.
HOWEVER, a couple of times i managed to upload actual files to iTunes U = they appear as APPLE HOSTED content. when i click on them within site manager they take me to a channel
I HAVE NO IDEA how i managed to create a channel, or get that content in there - it'd be very handy to be reminded how to do that.
As an aside... or... maybe central to this is that when spending hours looking for the answer to this question i went here: PUBLIC site manager help page - the content to that seems to bear no resemblance to what i see in my site manager... (the link above) click plus to 
in the course Materials pane for the course where you want to add materials.
where is that? is that on an iPad? am i missing some essential app that side steps the Site manage, that allows you to upload content?
cheers,
