a server with a decent amount of people
with no overpowered donor items

Your best bet finding a server with no overpowered donor items would be www.ratemyserver.net

However it'll be hard to find a decent server with no overpowered donor items ;(

I recommend RebirthRO, its excellent for pvm / pvp / woe and it actually requires patience to level up to max level whilst trying to get rich too. Also there are tonnes of helpful guides for the server.

100% Sure.

Hi, how can I change server ? When I launch the game, only one is available.

Well basically you have to redownload the client specific to each private server.

So if you wanted to play on rebirthro you would go to

www.rebirthro.com

and download from there.

www.dreamer-ro.net for dreamer etc.

Thank you boy :)
