Say a student misses a "live session" -- it's probably simple enough for them to go back and watch it? I mostly wonder about the videos, can I keep them and export them for archival purposes later? Can they be shared freely once a course is no longer offered, for example? Thanks it looks very nice and the interface is slick. The only rough edges I can detect are the "add your own image" headers and they are only a smidge away from full clean. I would like more imagery to explain what part of navigation I am currently in, but once I've read the titles it is clear where things sit.
