We've got 3 no votes, but they wont bear much weight unless they're explained..
well if we could use names instead of the ip then yeah that would be perfect but i think disable it really people abuse it and lie about names
mm this is a good point, I have seen people lie about names, or times where they were stirring trouble telling us who they were but they could have been anyone thinking back, because you'd take their word for it. The reason we have to auth on irc now is because of impersonations I was one of the people who were impersonated, would have been embarassing if it was not someone ingame talking to me on steam at the time.
Like I said though, there's no reason to use dynmap chat unless your causing trouble, or too lazy to auth on irc.
