Where to use siggies/urls ????

[EEYOREMAMA]

Besides these boards, are there any other places (like email) in which url codes can be used? Obviously I am technologically challenged or I wouldn't have to ask. But I am trying to learn and I see so many of my fellow posters who seem to have mastered this art.

If anyone out there can share their brilliant insight, I would really appreciate this. My DS would love to use smilies in his e-mail and my DH would love to be able to have a countdown where he can keep track of it. PLEASE HELP if there is some way to use these in the outside world (not that I actually live there).

Does anyone know? I'd love to hear from the outside world.
