Q: Challenge Responses

For challenge reactions, do people think it's a better idea to simply:

1) Create new posts?


2) Respond in the comments section?


That's probably the only other big question left; after this, I'll likely stick to a certain format, and we can switch it up if it doesn't work out.

I prefer to have a place to respond with comments.
But maybe people can make posts as well if they want to.
