Some people say that my messages are really long, and I've seen several times someone calling my messages the longest ones ever. But I'm pretty sure I have seen longer ones. There are some extremely long mod descriptions, messages with ridiculously long spoiler sections, really old fan fictions in forms of messages... All of this should count. Post links to some of the longest messages you have ever seen and maybe we can determine the winner.
1376 words, not bad. However the Gavril vertex page is longer: https://www.beamng.com/resources/gavril-vertex-na2.13061/ It has 1647 words (including stuff in the spoilers because it also counts).
