Mart - jumping in late here I know and hopefully everyone is past the whole conversation about the exclamation points but I just wanted to say that I also put exclamation points everywhere.
I think that when you aren't speaking to someone in person and you are communicating electronically where no one can hear inflection in your voice or see enthusiasm - it is the only way to convey that!!
So I also appreciate the excitement and enthusiasm of the marks that I use just as often!!
