Thread:Project:Support desk/Edit the Side bar

Firstly I am a new user to mediawiki and the wiki format on a very steep learning curve. The site is www.thehypnopedia.com I would like some clear instructions on how to edit the menu items on the sidebar rather than putting page lists and links. I am not a coding professional so any thing that makes my task simple would be appreciated

What i would ideally like to achieve is to be able to add menu items and sub menu items about 10 of each  for the time being with links within the information and community pages starting with the Main page and working down to the community pages / portal

My thanks in anticipation.
