You may request either NM or M4M. M4M better though if you need a mod (vs you want a mod). Chances of me accepting M4M are way higher too :3.
My m4m map is currently a WIP so I'm asking for a ticket. You can post how many minutes of the marathon you want to mod, and I will mod approx that many minutes of your map (rounded up to nearest diff).
Going to leave this open until I wake up tmr~ This is not first-come-first-served.
