Than vs. Then

If I write then revise will it be better than it was before? Or maybe I am supposed to write than revise to make it better then it was before? Once I get my rejection letter do I accept it or except it? Is it Neither nor or Either or?

I get so confused! Do you? I found a great site that has some fantastic word notes.

It is definitely worth checking out for all those little word issues.
