Summary box: Slydial helps avoid awkward exchanges

CONVERSATION AVOIDANCE: Slydial is a free service offering a reprieve from awkward or hectic moments by letting people leave messages for other people without actually talking to them.

MESSAGES ONLY: Slydial connects users directly with another person's cell phone voice mail, bypassing the rings.

BE SLY: Call (267) SLY-DIAL from a cell phone or landline that has the caller ID feature activated. The service generally won't work from prepaid cell phones.

Heck, it doesn't take a brain surgeon to figure out when someone is not going to be home and then leave a message!! That's what I do!!
