I was at a client this past week and they showed my how they were integrating Lotus notes and their MS exchange mail. I told them that I had wrote some code to do this years ago and had posted it in the sandbox. The client said "I downloaded this code from the sandbox". They were creating tasks and calendar entries in the ui then saving them to Outlook.
He showed me the db and wouldn't you know it was my old code from 1998. Still working today.
Made me feel good that something I shared way back when was still helping people.
