I don’t speak for staff, but can tell you that the last one was a disaster that had to be cut short. They ran out of nominations we could review. They will have to come up with a different kind of challenge in order to have another one.
In my eyes, the non-reviewing challenge for submitting edits was also a disaster. Many people got slapped with warnings for spam for submitting what we thought were good edits, and many others did submit spam.
I am not clever enough to come up with a different way to have a Wayfarer Challenge. They had originally wanted to have one per quarter, but I don’t see that happening.
