Database Upgrade

I think there must be some users notice that since 06/16 that there is sometime out of service, cause I upgraded the database.

There was a lot of trouble during upgrading, but I fix most of situation last night, so the system will operate normally from then.

I know there are many function can be upgrade, but I don't know how much time that I can do, so if there is anyone interesting this system, and you can help me make this better, you can tell me freely, I need all kinds of help beside coding~~~

Anyway, I make my apologize the system down without announce in advanced, cause the system is almost overload, and I make most of effort to fix the problem, thank you all folks.
