Call me crazy but I had a random idea pop in my head.... What if we all play a little game: Someone start by making a mod that consists of something small, that person then sends the mod to another person who adds something small... we keep going like that until there is no-one left to add something and we see what comes out?? MAY BE FUN??
HOW ITS GOING TO WORK 
-post your name in this post if you want to join in
-Ill send you the mod when its your turn, you add your mark, something small and return the file to me (so I can make sure it doesn't go missing)
-I'll then send it to the next person, Please only send the mod back to me privately (inbox me the DL link) so we can keep the surprise going
THE RULES-you must not reveal your part of the mod to anyone (I know the next modder will see what you did, but please keep it a secret as much as possible)
-you cannot edit someone else part of the mod.
-you may make your part of the mod work off of someone else's part (so if some one added iron for example the next person may see this and add a new sword and refined iron ect)
-try not to spend too long on your part, keep it nice and simple as alot of people will be adding to it
-YOU MUST NOT RETURN THE MOD WITH ERRORS
Im looking forward to seeing how this turns out
