What Mods Do You Think Are "Essential" to Have on the Server?

[Slay]

Well, I think the level mod was a great idea.
Dedicated forum members should slowly get bonuses on the server, something like every 500 blocks increase your level.

I thought the faction mod was a good idea, just to say that more than one person is working together, but that would more than likely lead to PVPing.

WorldEdit, to help the moderators out, and that is about it.
