I know this may be a personal preference, but I've always found it more user-friendly (from a student's perspective) to have the links (i.e. your github code and forum) open in a new tab.
Great idea. I need to go update my markdown parser to add
target: :blank into the links soon. I'll add that to my todo list. :)
