How odd.... based on the permissions, you SHOULD have access to make those edits. I'll dig deeper into the permissions junk tomorrow.
in the mean time, I've made those edits.... and please note: The "about_los" page has been replaced with "legions_of_steel" instead...
--edit--- hah... found it.
Apparently the page had been locked at some point during my set up... unlocked, you should be able to edit it now.
--edit3: for the lists, like the expansion items, and unit
lists, you might want to use the template function
, thus enabling it all to be formatted the same way (and for the format to be changed in one place for later updates)
