Let's make this as unnecessarily detailed as possible.
In the instance that I -
1) officially announce my temporary or permanent full departure from NinSheetMusic in the Official "I'm Away Topic," or
2) do not post or sign in (seen in "last active") in two months,
anyone may edit and submit my arrangements, provided that -
1) anyone interested in submitting regardless of completion must PM me in case of any objections,
2) if the arrangement is already complete, to submit it in my name, and
3) if the arrangement is not complete, to submit it as a collaboration between myself and any person(s) who edited the arrangement.
