I’m not to sure how far back, but I had made a post back during Milkyway 3. The title of the post was Conqueror of Worlds. There was very few places I had posted it, and it was more of a statement about reality/poem. I needed to find out if anything was saved that was posted in the old Forums back in the day.
I do not think forums go ‘that’ far back - back then, it was an IC-made only forum, so…not sure if they still exist at all.
But the most ‘recent’ ones can be found here: https://imperialconflict.com/forum/
