Become part of the community. That what you can do.
Also if you want to help the server get back on its feet help get the maps done. That is the sole thing holding this server currently.
No offense, but even if the maps were done, how long do you think it would stay busy? It's been a while since Johto was released and the server hasn't been getting much attention. Whenever I'm online, I see 2 people at most on the builder. You and stuff are the ones doing most of the building. The server doesn't just need new maps, but it needs playability. So far, all there is to do is challenge Gym Leaders, collect badges, and what have you. Sure, 1ce started making minigames, but we need more stuff to encourage players to come back. Perhaps hold daily events and specials. I even suggested the Underground idea to not only give players something to do, but also a way to obtain rare items as prizes.
