Let's hope not, we take bits and pieces of other succesfull servers and add it to our own, same goes for community suggestions and whatnot, combining all these separate slices makes one delicious cake
Add some more information about yourself, you also list previous experience, are you still active as staff on there or not, most people prefer a dedicated admin instead of someone juggling a handful of servers in rotation
In random order that's considered useful information: IGN, Age, Country + Timezone, instant messagers (just the programs you use like Skype/MSN), and wether or not you are familiar with control panels and FTP file managing.
So far i know if you want a remote desktop you are more looking at Dedicated servers, which can be customized to run any game program (usually)
If you prefer a pre-installed setup (with the basics), that's a Game Server, depending on your preferred hosting company there are many different control panels, some use custom ones and others use control panels made by someone else which they pay a license fee for to use, such as McMyAdmin or MultiCraft.
Custom ones are Clanforge (multiplay.co.uk) and Steve (global7hosting) as example.
With 50 people you will be looking at a server with at least 3 and preferably 4GB if you are going to run multiple plugins, it is best to go with a professional host, the cheaper the offer the less you get in terms of reliability, some even oversell their servers running more clients on it than the machine can handle, with all the problems that entails.
Turn your Monitor Brightness down whenever you encounter an Endermen, its a quick solution but should suffice until we can find the true nature of this mysterious problem.
I never make them, January is a mean month and crushes them.
If you're really fed up with an annoying habit/trait then most times you end up "fixing" it on your own, if not write it down somewhere to remind you, nagging works
