Did you mean the hidden bb code like this? Hidden Content: **Hidden Content: Content of this hidden block can only be seen by staff members**
BB Code is a markup language that is used on the Skyblock forums to edit threads. Whenever you quote someone, add hidden content, insert a spoiler, or even change font size, you are adding BB Code tags around the selected text. If you are interested in learning more about it, feel free to check out a guide, created by Lycel, here. If you are trying to embed an image that can be clicked on to give a huggle, similar to my signature, you need to go to the website, found here, enter your name at the bottom of the screen, then copy the BB Code link as shown in the following GIF.

Try changing it to something else, if this is the case. If it is still not working, please send me a screenshot of the error message you are getting, as well as the BB Code that you are trying to insert.
