需要发帖整理一些用户应当知道的事情

I'm not sure what to call it, but we could use a post that lists these things users should know. If someone has time to write it, here's the list:

• Make sure your clock is set correctly.

• Microsoft Security Essentials. This never got written up proper.

• Warning not to mess around with your wallet.dat file. It's a database file, it's not as simple as you think. In this Beta version, we haven't had time to try and tinker-proof it yet. It may not work as expected if you start swapping it around.
