You're not alone -
I too have not figured out the page numbering system;
[I gave up when templates were mentioned]
But there are simple solutions although not necessarily efficient;
either (1) wait until the paper is finished then insert manually;
or (2) insert manually as you write - in this method you'll
have to redo the numbering at times
or (3) skip the numbering
If anyone actually knows the solution to this problem, I sure wish
he'd respond on-list for all to see -
and in simple language, please.
