I have unfortunately fallen rather behind thanks to my full-time internship this summer -- I haven't had the energy to consistently keep up with things when i get back from work. :/ To echo everyone else, this course has already been an incredible resource; I think I've already mentioned to you that this is the first time I've really understood what natural transformations are! Category theory no longer feels quite so impenetrable, and I'm starting to see the right footholds to cling to.
It's also been a problem that the forum notifications no longer seem to be hitting my inbox. Being able to see how much activity has been happening from my phone's lock screen is a powerful motivator to come back and catch up on things, and without the notifications... well, out of sight, out of mind, as they say. I'm not sure if this is a problem on my end, but I don't seem to have any control over it.
