I've found myself repeatedly answering new player's questions regarding some of the systems that are already properly explained via Active Help pop-ups, because many players instinctively dismiss them without reading (a very common thing users do).
Recently, the ability to link quests into the chat was added into the game, which made me realize that it would be incredibly useful if we could link Active Help topics into the chat, such that when clicked by someone else, it opens up the tutorial popup.
This would make helping players easier, as currently you have to either explain the system yourself, or explain how to open the Active Help menu and what to search for to find the topic that will answer their question.
