Andre-
I noted a bug in the editing of subpages: For deciding
which part of the
page is part 1, part 2, part 3 etcetera, <h2> headers within <nowiki> tags
are counted as well. On pages where this occurs (for example
[[nl:Wikipedia:Te_verwijderen_pagina's]]) one therefore gets another part in
one's subpage-edit page than one intended.
Yes, this is a known bug and in my todo list.
Regards,
Erik
