This must have been discussed at length before, but i'm too selfcentered to pass the chance to create a new thread. Anyway, as I have learned english from multiple source, it not being my native tongue, I tend to mix up words from both american and british english. How bad a mistake would this be considered? Do people care or notice? Are there many authors who do this? I mostly do recognize the differences and know the equivalents of the words, but I wouldn't want to restrict myself without reason, and i'm lazy above all.
