Hey Nicholas!

 NB> getting nano fixed was quite a few years ago already.

Those were the days.  ;-)  Anyhow I think you underestimate the potential of that fix.  From fts-0001.016 I take the liberty of quoting;

 fts-0001.016> Message text is unbounded and null terminated (note
 fts-0001.016> exception below).

Being unbounded is what makes any resolution possible as per character display rows and lines are concerned.  For me 4K Fidonet worked right out of the box and with some tweaking (the fun stuff) I am able to create some very unique MSGs while adhering to acceptable FTN standards.  Not many can make that claim today.

Having said that I believe fidonet required a good enema more than 20 years ago.

Het leven is goed,
Maurice
