How to gain R/W access to developers wiki?

I want to collect all XML todo issues (from my list, from Peter's and
those Tom just described in "Loose ends in PG XML patch") in one
place, to make the overall picture clear for everyone.
How can I gain access to developers wiki? (Actually, I've created the
page"XML Todo" - http://developer.postgresql.org/index.php/XML_Todo,
but it's locked for editing).
