Personally, I’d love it if we could do an IRC-channel link. Yeah, I know there’s the App out there, but an IRC channel is nice because it’s relatively easy to manage, and doesn’t take a lot of processing power to run it in the background. I might be the only one, but it’s kinda hard to have both the game running and the Dynmap on my connection.
Also a LOT easier to kick spammers from an IRC channel than it would be from the Dyn. A server I was on had CraftIRC, I believe. What was said in the MC world was put into the IRC by a bot, and you could “/say” in the channel, or something like that, to have it go to the MC world from IRC. So it could be a hangout for people that can’t get online at that time for … whatever, but still allow people to interact with those that were online.
I’d love it if we’d look into it, but I kinda doubt it’ll happen.
