As a server owner: It's a pure forge server or you will be using bukkit plugins? And, if you're not going to use bukkit plugins, how will you manage griefs? Which items will be banned? It's a premium or no premium server? If it's no premium and pure forge, how will you deal with hackers? There's whitelist? Which are the rules? Do you have any web? And I still have got a large list of questions remaining.
Think about everything and don't focus on opening quickly, or you'll get a headache trying to deal with those things on the fly (and if you already thought about it, explain to your potential users how will everything work)
