So, the sandbox is now up, and there's a decent amount of activity. I like what I'm seeing: good dialogue between users on the posted questions.
I'm suggesting that we use the sandbox for answers, too. I'd like input on one I'm working on, and I daresay others would like it, too. Should we use the sandbox for this?
I'd advise not voting on this question; please vote on the answers posted below.
Another suggestion of mine here would be to not downvote any answers. That way, we can gauge the support of each option better.
After being away for some time, I see that things have gotten quite interesting. Four people have done what I said not to do and have voted on the question, while three have done what I said not to do and downvoted an answer. Ah, well, I shouldn't tell people what to do, as this is an issue for the community, not me.
Adding in ArtofCode's vote, the winner appears to be the option of having a separate sandbox. I'll leave it up to ArtofCode to create it, as s/he created the original one. In the meantime, feel free to voice any and all objections on the matter. This case isn't closed quite yet, though it may have reached its resolution.
