Eeky, first of all thank you very much for your feedback, I really appreciate you taking the time to respond. Also, I am sorry you have difficulties accessing the forum.
We have had a few server hickups last Sunday around noon JST and today, too. I have not been able yet to determine what caused them, but generally the server appears to be working fine. I have tested the forum in Firefox 7 (my default browser), in Opera, Safari, Google Chrome and just a tad in IE8 and 9. I have basically stopped using Internet Explorer since version 4. I cannot reproduce the server lag from here, but I'd appreciate more feedback in case other members experience the same problem.
