>Hi everybody,

>The word "advice" is a noun, while "advise" is a verb. However, I see lots of messages, even from the native speakers, where "advise" is used as a noun. I'm wondering, what other examples for "c" in a noun and "s" in a verb exist?

I'm sure it's just a question of poor spelling. The same as when people use loose when they mean lose.
