Of course what "a few minutes" actually means is anyone's guess as in my books "a few minutes" past "a few minutes" ago and it's still not working...EDIT: Whilst I couldn't access Gmail (I can now btw) I was still able to download all my mail into my Outlook Inbox and read it there. Anyway, problem seems to have been resolved now. Glad people also chimed in about their accounts as I feel slightly relieved it wasn't just a fault with mine like it sounded - although I did have Dave come downstairs to let me know his wasn't working either.
