I miss the entire era that came with it sometimes. Not specifically the software, but that is what connected it all...
https://www.facebook.com/officialmsnmemories/ nails it.
The going home from school an "We'll talk on MSN". Spending the rest of the day on there until deep in the night. Teenage drama, talking behind people's back in group chats, passive aggressive blocks, spamming sign-in notifications, making friends around the world. As snapchat may be for some of the current youth, MSN shaped my teenage years. I'm in my 30s now, times are different. But I have a lot of fine memories around it, which is also why I wanted to keep the forum archive around.
