The server is way to laggy to play on, it's not completely unplayable, but it's frustrating enough for me to go find an alternative.
There were 6 people online last night, and nobody complained of any lag. I'll talk with Kodlee and see if he's using his server machine for something major other than Minecraft that might be causing this.
I'll let you know once we've addressed this issue and done everything we can from our end. From there, if the lag persists, I'm afraid there's not a whole lot I could do. Sorry for the frustration, mate, I can't stand lag either.
