Three day weekend over, so it's time to be back at work.
I made some progress today (and cleaned up a few lines of questionable code in my own area, just so you understand that I make mistakes). Unfortunately, a lot of the other stuff that I was looking at needs some refactoring, which turns it from "fix a bug" into "this is a project".
I do not need another project right now, especially in code that I'm not that conversant with.
We'll see how it goes.
