Well i got this idea from musik's post, But i don't wanna just talk in that post because i don't like the idea for a "mapping committee",
I think there should be a monthly mapping competition like the GGC, Which is held rarely, We could use the same format, "Admin" selects a theme, and you start a new map, It cant be started on before it was announced, Beta's are allowed, Maybe 1st 2nd 3rd place prize, So tell me your thoughts on this.
ALSO, maybe if you wanna make it more of a challenge, When telling the theme, The admin's also select a certain brush, Like for example, This months theme is Sci-Fi, The map MOST include a ufo brush/model you made
