Thread:Project:Support desk/Editing the horizontal menu array

By horizontal menu array I am talking about the menu at the top right of the page the contains the links for "my preferences", "my watchlist", "log out", etc.

I would like to add a link in that menu array but cannot find any information to do that.

I am using 1.16.0 and Softbrown skin (which has this menu array at the bottom instead of the top).

How can I add an item to the menu array?
