I tihnk that you should extend the player count in smp3! It takes me 20 minutes ot find an opening in the server!
You are playing for free , and others are paying for it We should be ready for smp4 soon, also: http://empireminecraft.com/threads/i-think-you-guys-should-add-more-slots.1242/
you have to understand that you are not the only one who is waiting. and even if slots were added, they will instantly fill and then you will ask for more, and the issue with this is, 45 is the number the empire hardware funtions the best on. I feel like i am saying alot of what the thread justin linked you to says. This makes me feel like you didnt read it. So please read jeremy's thread and try to understand that the empire is doing everything it can to keep as many users on as it can. You will have to be patient.
I think u can go buy supercomputer with 1Petaflops computing power and 1TB of Ram and donate it for empire. that should get u what u want. and donate a 10GB/s internet for empire too maybe u get to be life-time diamond supporter for doing that. lol
