How do you spell modding?

[PvK]

RP "moding" is apparently pronounced the way it would appear to be: mode-ing. At least, a couple of the articles I found dealing with the term also use the present form "to mode". I am still wondering what the etymology of the term is, though. I think it is probably refers to a mode of roleplaying speech. There are then sub-types of moding, and the articles I found all were relating to improper roleplaying, where a roleplayer would speak in a mode that game them control that their character would not have, by saying what other characters do, or by acting based on knowledge their character would not have, or by claiming to do impossible or near-impossible things.
