Looks like Uboachangot a bit of an update. Specifically, .flow and 2kki no longer have their own boards and discussion relating to them now just goes in /fg/. Similarly, all character-specific boards (i.e. /mado/, etc.) have now been combined into a single “characters” board.
You can apparently still see the old /2kki/ and /flow/ boards, but you can’t post on them anymore. Interesting changes. Kinda neutral about them myself, but I’m not sure what other people think.
