In fact, it
would be even cooler if I could have not a page reference,
but plaintext preloaded, like
<inputbox>
type=create
width=24
buttonlabel=Create me!
preload_plaintext={{person}}
</inputbox>
This means preloading a template? This is possible. Look here:
http://meta.wikimedia.org/wiki/Inputbox#Preload
I have read that, of course. I would like to have "{{person}}"
preloaded in the page, not the content of Template:person.
Cheers,
