I am using a web mail (cox) and chrome. Your e-mail doesn't have a link on top for "if you can't see this in your browser", which would be nice as going to the home page doesn't show the current e-mail information. ie Sonic Screwdriver by MrTinkerer
I've never seen the above warning before and it doesn't sound like one I want to see. ;-}
