I was surprised to see both of these on a recently published spelling test with definitive spellings. I tend to view alright and alot as a more casual (or colloquial) conversational usage, and use it interchangeably, but I always wonder in print which form is best when I do.

formal): There is a lot of money.
casual): We do it alot. We go there alot. We ask alot.

formal): You got the answers all right. Everything seems all right for a moment.
casual): Alright, I'll be there in a minute. It's gonna be alright. That's alright with me. You're gonna get it, alright!

Interesting...I find it more difficult to come up with formal examples of "all right" than I thought.

I was wondering about everyone's habits of usage for these.
And does the OED sanction the alright/alot forms?
