Hi, I'm sort of new to Bukkit (2 weeks) and I'm really really loving it so far. The community is great! I run a relatively small server, with 5-6 of my personal friends on at a time. I try to keep my server as legit as possible, trusting my friends to not abuse any of their power. It's not been working out so well. How can I disable /tp and /give so that only admins can use them? Can someone give me some sort of guide on that?
