Thanks mate. You don't need to call me sir though. You can call me Arif or cryptofiend or whatever you prefer:)

I like the Arif name. Different then what we hear in Canada.

Don't worry about the Sir calling. Everyone is a sir. :)

Lol yes it's not very common.

You are very polite my friend:) Actually I used to do it a lot too because I went to a very old fashioned school.

I'm not being critical - it is lovely really so if you prefer that then that is fine:)
