How to move for sale post from one exchange to another

[Pete G]

I posted a for sale item in one for sale exchange/forum and wish to move it to another for sale exchange/forum.
For example if posted in shotguns exchange, how to move to rimfire exchange ?
I have seen where others have done this, but I do not know how it is done.
Any assistance will certainly be appreciated.

I would delete it (please remove) then
post it in the rimfire catagory.
