You say adviser, I say advisor

I've long longed for an official job title. My business cards say I'm a "financial services professional," which doesn't really promise too much, but at least makes me into a professional something. When I meet people, I tell them I'm a "financial adviser," which has some instant name recognition. But if I have to put it in writing like I did just then, I get confused, because I want to type "advisor" which gets the spell-check red line treatment.

Go figure I would have a job with spelling issues.

Since my job is to know things and then share my knowledge with others, I did some research on the spelling of things. My first source was Dictionary.com. Not exactly helpful, as it gives a definition for "adviser" (one who gives advice!) and follows up with the vague, "also: ad.vi.sor."

More helpful was Fluther, a website I found by googling the phrase, "adviser advisor difference." It turns out that the English language is a beautiful thing, and if enough people do something wrong enough times, it becomes okay OK.
