You already know this I'm sure based on your join date, but BB Code is allowed and the link is at the bottom of the page. (per attached pic here). I agree that no hide code is available. I also found this to be an issue when browsing through certain sub-forums here. For example the Case Modding sub-forum where many of the pages have dozens of uploaded pictures on each page of a thread. Takes forever just to load a page and read the thread. HIDE or SPOILER feature would be great for that application.

Maybe one of the moderators here has access to the forum settings to add it ?
