So recently I decided to make a server with a friend. I made the server successfully (I hosted it for free) but when it came to adding plugins... Well I couldn't find anything! So I don't know how to make my vanilla server into a bukkit server for free. I was wondering how to add plugins in a vanilla server, or if I could add bukkit for free, that would also work.
I am using a Mac book pro 2010 build.
