Our IT installs forum upgrades regularly, usually just little plug-ins and mostly anti-virus stuff since forums are rather susceptible to them, or at least so I'm told. Usually it goes smoothly and the only difference you might notice is...well, you usually don't notice anything. It's all in the admin. Something went wrong with the last one and we lost a day's worth of posts. Our apologies. Such is the nature of a web forum. It can all be gone in the blink of an eye.
