I am fairly new to Bukkit, it's been working great for me so far. Basically i've been running a small server just for my friends, and I wanted to be able to invite guests to view my world but i've been reluctant because of griefing potential. I already have permissions configured to make admins invulnerable and able to build, and anyone else not able to do either, but what about slash commands? Is there a way to deny these specifically? I just want to make sure that there's no way that guest players can do things like unbind my portals and stuff. Also, is there a way to make sure players have to be authenticated with a real account to come in? I figure this would help reduce the likelyhood of shady characters potentially finding the server and coming in (i have both daily backups and shadow copies every two hours, but still). Nothing is really preventing someone from finding my server randomly or by port scanning and coming in. Any help and/or suggestions would be appreciated.

My server permisisons are set through the Permissions plugin.
