I've noticed something interesting, and would like to mention it.
Ever since I've been learning Russian, and when I study, I often misspell or forget how to spell English words. It's interesting.
Have any of you experienced something like that in learning English?
I'm a Russian major in college and an American. I definitely know what you're talking about with starting to mix up the Roman alphabet with the Cyrillic one when writing in English. Once I got used to working in both languages though and it stopped happening as much for me.
