As per Let's allow newer languages/versions for older challenges, we no longer need to mark answers that utilize languages created after the challenge as noncompeting. However, there are still 917 + 207 = 1124 answers with that word in the body or header.
I think they should be removed as they add nothing of value and are just an eyesore. However, I'm not going to do it all in big chunks by myself as I don't want a re-do of my Sandbox flood a while ago. And Martin told me not to.
So, can we set up a time or date when people can go through all the instances of "noncompeting", "non-competing" and "non competing" on the site, finding which answers need to be deleted (as some users mark invalid answers noncompeting) and which ones simply need the word removed?
