I've just about recovered from a huge crash on my PC from which I send and receive emails. I maintain records of all emails back to 2001 (over 600k emails!) so it took some time to organize things. For the rest of the day I'll just catch up on responding to emails. If you don't get a response today, it will be Monday. FYI Thunderbird is pathetic at system restores, don't use it if you need a robust solution.
