I'm for example in world 23 and my friend has downloaded this game and I want him to go with me in my world (23) how can he choose it and start a new game there? Please i need to knoe this. Thx.

Unfortunately he cannot join you in earlier worlds. But you can join him on whatever newest world out there.
Would be nice though if they can join you in older world. The only thing is every world is capped with a population limit.

:S thx man. It would be nice that new people could join older worlds or wichever they want without problems. But thx anyway ^^

If so, why is it that once in awhile I get to see the population increased by 1 number? E.g. The main population is 58,331. Then the next day it increased by 1 to 58,332? And of course I'm talking about older world...
