Liability once LLC is closed?

My colleague has ably answered the possibilities and scope of potential personal liability when the LLC is dissolved. I would only add that while operating the LLC, you need to be careful to only do business as the LLC, with all contracts, business assets, etc. in the name of the LLC nad not your own name, and you need to observe the few LLC formalities that exist. And, if you are required to personally guaranty any of the LLC's obligations, such as for a loan or a commercial lease, then you could incur personal liability.
