I feel like one of the main difficulties of having a massive sandbox is the difficulty of seeing all of the posts in the sandbox. There are 63 answers in the XIV sandbox and 66 in the XII sandbox, and I'm pretty sure I've never actually seen most of those submissions.
To increase the visibility of all of the sandbox posts, I think the body of the sandbox question could provide a list of all of the active sandbox submissions. When people casually open the sandbox, they might see something that catches their eye.
When a person adds a sandbox answer, they add a link to their answer to the directory. When a challenge is posted, the user moves the link to the list of completed answers.
This is basically what I envision it looking like:
- Draw square numbers in the shape of circles
- 1000 blank white cards KotH tournament
- Compute Graham's Number in Manufactoria
Slight side note: I am using the [ ] ( ) form the links.
- [Title of Answer](URL to answer)
The use of the question as a directory has the advantage of recording the history of sandbox use, so that everyone can see exactly what posts are contained in the sandbox and where they are in development.
It would be convenient if there were a way to automate this. For now, I think this is something that the community is capable of maintaining, similar to how people already edit their sandbox posts to denote a posted challenge.
