Quoting a Closed Topic
I’ve been finding quoting the Big Review Guide really useful recently, but I’ve noticed quoting a closed topic isn’t as easy as quoting an open one. Luckily I have a workaround. 
If you open your reply editor in any other open topic and start typing, then minimise it and navigate to the closed topic you wish to quote from (eg the Big Review Guide), expand the reply window again, and you can then highlight quote as normal. 
NB You must have your reply window expanded for it to drop the quote into the existing draft (on my phone I need to minimise the keyboard to free up screen space). If the reply editor is minimised quoting will open a new ‘reply as linked topic’ message and put the quote in there. But if that does happen you can simply copy the quote section and navigate back to the original reply and paste it in there
