Hmm... I submitted a puzzler... doesn't show up. I suppose they're getting moderated.
Yeah, I submitted an answer to the first puzzler, and the comment was pending moderation until some time this morning. This seems to be a side project from the author of codeanthem.com, so I wouldn't expect to see fast approval of puzzlers / solutions by a human any time soon.
Puzzler answers used to be moderated (but now show up immediately).
Puzzlers are only published once a week and are hand picked.
