This literally has been an on again / off again project of mine. Years ago a bunch of friends gathered around a Yahoo Group called Marcon Drinkers. This was our social watering hole. Now the site has more or less dried up and only still exists for nostalgia reason. I’ve always wanted to salvage the data out of there and there was never a good solution.
I have now found one.
Thanks to a perl script located here I managed to get all my data out. Now I can be happy and never have to contemplate the dreaded copy and paste approach for over 4k messages.
