That's a relief then :D
I'll give my best to work on it :)
It's probably a mix of all of it :D
I did set my spell checker to British, but there are probably a couple of typos/Misspellings regardless. Some of them get highlighted because I'm not sure (like Neville saying "gran" - I'm not sure if I should capitalised or not) and others probably move right passed my attention.
I once noticed in a fic that I printed years later that I wrote "sun" instead of "son" :D
