Not only that but GW2 also can link items and skills in the chat so that someone else can view them. And the best part is that this also works with the wiki command.

So, for example, you found an item and want to know what it is and what you can use to for, just link it after /wiki and you are redirected to the full page of that item.

Unfortunately, I lately have issues with firefox in which the first wiki command somehow screws with my firefox and thinks that it needs to restart before being able to work correctly.
