Only have 3, usually during the week I don't have much time to chat due to working early mornings and mid-evenings at the same job.. But occasionally I'll shoot someone a message while at work at night when I'm waiting on drivers to come back to work so I can do end of night paperwork.
I have more from business than friends. Young engineers love to BB Msg. me it seems. My firends prefer email perhaps due to the age group (Snr Citizens :>)
