Editing a page

Hi,

I love the Web Curriculum material, and have pointed countless people to it
forever.
I would like to fix this page:

http://www.w3.org/community/webed/wiki/The_CSS_layout_model_-_boxes_borders_margins_padding

In particular, there is a formatting problem if you look for the
string "properties
commonly accept any of the following value" (the following line should be a
point list).

I created an account, 'mercmobly', but still couldn't "login" in order to
change the page.

Do you need to approve me somehow before I can edit things?

Thank you,

Merc.
