Okay so I was making a discussions post on the BGT Wiki informing every editor and/or visitor on the migration to Fandom Desktop. At the end of the post I linked the wikis rules for anyone interested in reading them, but before I did that I checked what the protection on the page was, but when I clicked that I noticed another button between the Move & Protect Button known as Purge. As an admin on that wiki I clicked the analytics in order to look at them and clicked the lighting button expecting to be taken to a lighting settings, but it just changed the lightings so I changed it back to the original lighting. But I hadn't tested or looked into the Purge button and I am wondering what it does, however I don't care to test out clicking on said button until I know for certain what it does in case it's some other form of delete or anything else that I don't want to click for any kind of reason. Granted, I could create a blank page and press the Purge button on it, before deleting it, but I don't really want to do that, but if I were to do that and make a page that already existed and click Purge on the new variant would it possibly work as a merging button and merge the two together?
Edit: For anyone else who is interested and is yet to test what the button does and is confused as to what it does, I've just tested myself by creating a page known as Test as I changed my mind after making this post. For anyone interested the Purge Button takes you to a settings screen of sorts and asks if you want to clear the cache of the page, if you change your mind click back and go back on the page but if you still want to purge click Ok. Beneath this is a message which states 'Purging a page clears the cache and causes the most current revision to appear', so if your reading a page and someone else is editing if you click the purge button and click ok when just as they complete their edit the page will have their edit added to what you were previously reading.
