Email Addresses

I've not posted a blog in years, but I feel I need to start ranting about things. Maybe ranting is the wrong word, but basically I want to stress my frustrations and opinions.Well one thing that really winds me up is people that write their email address in sentence case i.e Firstname.Surname@domain.com agggghhhh. Email addresses are supposed to be in lowercase!!! Pisses me right off! Maybe I'm being a bit over the top, but who cares? lol
