We're not trying to change the way it's spelt, just standardize it. And Joann is JoAnn, probably the reason we're doing it (not).
Here in San Berdoo, we have a street named Base Line. It was the surveying base line in 1620 or whatever. In its length it's spelt Base Line, Baseline, Base Line St., Baseline St., Base Line Ave., Baseline Ave. and maybe some more.
But Base Line is still Base Line, no matter how it's spelt.
As is Speedweek, SPEEDWEEK, Speed Week, and SpeedWeek.
(By the way, the campaign is 3 years old and hasn't made much progress.)
