Carl, here is what you do.
Go to the wiki and do a search for Location Codes, since nothing is created for that it will ask you if you would like to "create a page"
Hit yes,
Add all the content you want, when you are done go to this page:
http://www.pbxinfo.com/wiki/index.ph...ramming_Guides and click edit on "NARS and BARS"
Then type in [[Location Codes]] right below it to create a link back to your new page you created.
and that is how you use the wiki. Just make sure you add a link back to the main programming page after you create your article.
