[website-dev] Categorising in the wiki

Hi all,

I publicly admit that I am outstanding at forgetting to categorise
wiki posts - I helped categorise many of the wiki's uncategorised
pages, yet when I create new pages (thankfully it's not very
frequently) I often forget to categorise them appropriately. So, I
started wondering if it might be possible to edit the editing page to
provide a clear reminder about categorising - above the save button,
for example. Or maybe there is a plugin that does something similar?

Regards,
Ivan.
