Hi Anon,

If you really want to thank Clive, just say 'Thanks'.
Hi,

That's OK. I guess 10x means ten times thanks, so that's ten times better!

Best wishes, Clive
The second of the four sentences is a bit of a 'garden path' sentence. Since check can take an object like the main electricity supply, I would have included the that for stylistic reasons. This blocks the interpretation having checked the main electricity supply, which leaves the reader wondering why another finite verb is added (had been switched off) instead of a non-finite construction such as to see if it had been switched off.

I too would add "that".
