How to get edit rights for CXF Wiki

[Andreas Bakurov]

Hello, I am user of apache CXF and sometimes, while I am reading CXF
documentation, I want to add more material or perform some cosmetic edits
(like correcting anchors etc).
I believe that the quality of CXF documentation still need more
improvements, many details are ommited.
What I should do in order to get "write" permission on CXF wiki ?
