I think you are right, I copied it from somewhere else...I guess they were wrong as well.
Too late now.
It's not too late, fix the misspelled word. Years ago I was reading a trade mag from the lawn & garden industry and there was a very informative article about signage. The thing that stood out most to me was the part about misspelled words. The motoring public was broken up into three categories.
1 - This group immediately notices the mistake. Their first impression is that you are an idiot.
I fall into this category. I spell very well and notice mistakes all the time. My first impression is that they are incompetent morons. They usually are just as competent as anyone else, but they don't give a good first impression and you don't get a second chance.
2 - This group notices the mistake and thinks nothing of it.
3 - This group doesn't notice (no harm, no foul).
Long story short, do you want 1/3 of your potential market to have a first impression that you are an idiot?
