Q. How do I unlearn a skill? (Torux)
A. Open your list of skills ('k') and click on the tradeskill you wish to unlearn. At the bottom will be a description of the skill. Next to that is an icon that you can click to unlearn the skill. Be warned, this will completely remove any knowledge you have of that skill, and therefore if you wish to relearn it in the future, you will have to start from the very beginning.
That information and so much more is found at the top of this forum under the title "Trade Skills Sticky".
