I am new to moodle, to understand the "language editing" option I followed these steps and have been struggling with the problem for some time now.
I logged in as administrator and selected language editing option, and after choosing "Local String Customization" of English Language pack, changed the entry against "Author" to "Contributor" and saved wiki.php.
I was expecting to see "Contributor" instead of "Author" on the refreshed "wiki.php" but it was still showing "Author"
Can you please point out error in the steps i have taken. I am using Moddle 1.9+ on windows XP.
