Hello, I'm oberdiah and I'm 14 and my skype is oberdead. Although I feel that I'm not 100% at building spawns and arenas, I have many, many ideas for new minigames that your server could have, boosting it massively. These ideas include, but aren't limited to: Lavapocalypse, lavarun, m4yl, eeo, the4teams and kto.
I would rate myself a 9/10 for redstone, but that isn't much use for a minigames server.
I don't have many examples of my builds as I don't do much, but if you look at my profile then you'll see a few projects.
I have been trying to start a server for the past 6 months, but never really managed, mainly trying to get my minigames to work on my own.
Hope you consider me as an option, even if it isn't as a builder, oberdiah
