I was just reading this article and found it interesting. It listed the following as the 5 biggest mistakes made by an LLC:

1. Before the LLC Business Entity is Formed, Don't Conduct Business.
2. Failing to Actually Issue Ownership Interests of the LLC Business Entity.
3. Failing to Create a Management Structure and Appoint Officers for the LLC Business Entity.
4. Failure to Get Investment Obligations in Writing.
5. Thinking that an LLC Business is a Foolproof Layer of Liability Protection.
