this works indeed! i had disregarded it because of the wiki description:

MN - Network address of current message base

which to me meant 1:2/3. doesn't seem to be publically editable or i'd fix it right quick.

but, i have to introduce a different issue:

QWK networked bases show as "Local Address" :)
