Given all the recent discussion about banners and tags, I raise the following question: should we request a warning pop-up whenever someone tries to create a new tag? Apparently this is possible and would look like this.
I doubt it is possible for each site to request custom wording, but if it is possible, I would request even stronger wording. Perhaps the last paragraph could say:
Creating a new tag is almost never the right thing to do; most new tags require an approved proposal on meta.
