comment #58577 Please mark oekaki accordingly. It's much easier when people tag pics on upload, rather than relying on someone else to got through and add all those usual-but-omitted tags like oekaki, monochrome or sketch.
I tag artist, character, and series. As long as a post has those, I'm happy. I also try to add other common things I care about, and monochrome is usually one. Oekaki generally isn't one of the ones I make a special effort to remember to add.
If you want to add anything someone else leaves out, you'll have to do it yourself after the fact.
