The first sim created in Phoenix (in fact it was intended for DDC) looks like being the first to hit the 1000 post milestone.
With 946 posts in 20 threads at time of writing; it is 190 posts ahead of Jericho, another sim inspired by Firefly. The third most posted-in sim is The West Star, in the Star Wars section.
Atlantis is actually more popular than every forum except Management.
Well done to Mike Palmer and his crew!
