How Many Succesful Servers Have You Had?

I had a semi-successful TTT server, alongside a semi-successful DarkRP server. Those were my first two servers.
Then a few attempts at making something good which didn't work out.

Eventually later I became Developer for a rather successful community, and owner/developer of another rather successful server.

So I've had my fair share of successful servers.
But I've had just as many, if not more failed attempts.
