It depends on your settings, you have a lot of control over what notifications you get. Click on your profile pic and go to Settings > Notifications

Edit: pretty sure it notifies you by default

Also the glitches don't really have community-agreed names, the ones I used in the guide I just made up on my own. The names you use in your guide are as good as anything

Nice! I added this to the guide section. I also just added a document I made detailing level-specific information which may add some useful insight for what's happening in ThxFor's WR route.

One thing I'd note is that Full Game Any% routes are different from IL Any% routes because the former is timed with RTA and the latter is IGT. IL runs let cutscenes play to specific times in order to line things up and that can completely change the route
