"The idiot users who delete them because they don't like the look will have to learn, like everyone else has done till now, not to change the extension."
the idiot users are your clients, the same ones who will complain to you and cost you money when something breaks, also liekly to go moaning on a forum somewhere to generate bad publicity when idiot ms haters find it much like the fact that autorun still pops up is being used by ms haters, as they forget that fact that the trick in questionis actually closed because you can't create your own tasks in there!
