AIM (AOL Instant Messenger) will be taken offline this Friday, 15 December 2017. It has been years since I have used the service much, yet I have kept my handle in continuous service since 1998. That’s over 19 years.
AIM was able to give me a readout of the moment Brian and I joined. See “Member Since” in the images.
ICQ was our first messenger in 1996. I still keep that one in operation, too. UIN #1564254
These days, people use services like Signal, Telegram, WhatsApp, and others more.
