It was so exhilarating sending and receiving POP3 email for the first time back in the mid 1990s.
Messing around with Geocities, chatting on mIRC, downloading tons of freeware and shareware on download dot com (before Cnet's tomfoolery later on).
Later years, defaulted to Outlook Express. Then switched over to web mail. Back to Outlook/Exchange at the workplace.
