Unfortunately, you can’t quote posts from closed topics unless you have mod powers.
…Or can you?
You can, but it requires a bit more effort than highlighting the text and hitting “quote reply”.
Let’s say you want to quote a post in the “BIONICLE memes” topic on the 2017 discussion topic, for example. First, you start by opening a reply on the 2017 topic and typing enough text that you can post. Then, with your reply box still open, you go to the BIONICLE memes topic and then hit reply. A box will come up asking if you want to reply here or on he 2017 topic; choose to reply on the memes topic. Unless the boards glitch out, it won’t let you – a pop-up will appear explaining that something has gone wrong. HOWEVER, your post is now considered to be a reply to the memes topic and not the 2017 topic, so, by clicking on the speech bubble in the top left corner, you will have a quote of the first post in the memes topic. You will have to change “full:true” to “full:false”. If you want to quote something besides the first post, you’ll have to change the username and post number (Or just the post number, if you’re lazy). Then you go back to the 2017 topic and post.
Ta-Da!
The only solution I could find was to use a picture hosting site like brickshelf. But I don’t know much about file linking, so I’m afraid I really can’t say more than that.
