Yes.
2. Have you ever posted art in the oekaki weekly challenge board before? If so, how many times have you joined the challenge?:
No / Never.
3. Do you think that the oekaki challenge time limit (1 week) is enough time? If you think it's too short, how long do you think each challenge should last?:
I think 1 week is fine, but some people are a bit slow when drawing so I think 2 weeks would not be too much for them.
4. Do you think the old themes should be used again sometimes for people who missed them?:
Why not

5. What do you think about the themes we've used so far? (some examples were to draw your fursona as another species, or to design a character inspired by the current season)
They were great themes

6. If you're someone who uses the oekaki but doesn't use the weekly challenge board - tell us why you don't use it:
I guess it's mainly a lack of motivation and drawing mood. I already considered joining the challenge a few times, but I also have other drawings and things to do first, so it's not really my priority.
