You're right! I should have typed "must have gone" instead of "must have went." I've been exposed! I also like how you noticed that. Most people don't see errors like that. I see errors in your posts all the time.
Haha, I'd appreciate you pointing them out! I have got a CAE, but I still think I've learnt most of my English from the internet, so that means I might also copy others' mistakes. Side-note: I'll be reporting the OP to have its title changed, making it more obvious that it wasn't me who started this thread.
