# This script is inspired by "im_typing_notice" for irssi.
# It creates a new bar item displaying when contacts are typing on supported protocol in minbif
# It sends a notice to your contacts when you're typing a message.

# Author: CissWit cisswit at 6-8 dot fr
# Version 1.0.1
#
# Changelog :
#
# * 1.0.1
#   Ignore the user "request" (no need to tell it we are typing)
#
# * 1.0
#   Original version
