level

i see i can send resources to the farms i have conquered on my island...when they receive enough they go up a level. my question is if i level one of my farms up does it go up for the other players on the same island ? or does it just benefit myself ?thisisgrepolis

So, I am guessing that the population would cease expansion - once it reaches level 40? Geez, haven't these citizens herd of.... oh nevermind.... So, I suppose the only question that would remain (out of mere curiosity) is rather or not it would be possible to demolish the farm and start...
