Hi I just downloaded you mobspawn plugin (http://forums.bukkit.org/threads/fun-mobspawner-1-8-spawning-mobs-by-command-or-sign-1337-now-with-spiderjockey.15528/ this one) works great however does not spawn endermen. I left a reply there but I think it got buried any assistance would be great. thanks.
p.s. I run windows 7 if that matters.
