I promise I scoured the boards to see if this had been discussed elsewhere, but couldn't find anything about it. I am wondering how each of you approaches the spelling of, well, cum.

From the look of things, my editor assigns "come" to the verb - the act of it - and "cum" to the noun - the mess of it. Is this correct?

I know I'm in for a thread full of puns. Come one, come all, come on, everyone.
