A few months ago before I head off to Vietnam for my vacation, Rocknarok/TRRC had a weird bug. I personally call it, the X001A Virus.
Virus/Bug Code Name: X001A Virus
Desc: It wipes out a lot of sections in the forum and block access to them even if you have the URL. When it took place: Somewhere before my vacation on 20th May 2010.
More information will be provided when the Head Admin of the Forum returns. Hopefully he does...
