It's dated, but I still use it

I still use IRC program. I have friends in the U.S. that we have 'conversations' just about once a day, unless either of us has early morning (me) or going to be out working late, or going to crash early (them).  Also use Skype

It's an inexpensive way to keep in contact, and not have to worry about being in my jammies, or mussy hair.
