I'm sure there are some groups on FB that better engagement than that, I've used the messenger function on it recently, but that's entirely different.
As to Excel and numbers - that's the basis for making lots of pretty graphs and things, beautiful!
Hehe - I have an Excel happy boyfriend, so it's a classic 'tease' between us, I will 'just know' my decision, he will have to put some numbers in Excel first :D Often we draw the same conclusions though, so it's mostly our process that's different :-)
