Forex Factory Knowledge Base

Where to find announcements that affect Japanese yen? I noticed that there was unusually large movement on the GBP/JPY currency pair in the end of October '08 to the beginning of November '08. I looked on Forex Factory for an explanation, but found none that would explain that kind of movement. My question is twofold: 1) What caused such huge movement in this market at this time? 2) Since it's not on Forex Factory, where else can I find a heads up about whatever caused these huge (mainly bearish) runs?
What does forex factory mean and whats its importance to forex (Foreign Exchange) I would be greatful if you guys can tell me what you know about it and how it works
