Where can I find guidance on bank's presence on social networking sites such as Facebook?

The only guidance I found was the following question listed on the FDIC Compliance Exam Request List:

“Does the Bank or any representative thereof offer, participate, or maintain a presence in any blog or social networking site(s) such as but not limited to such as: YouTube, Facebook, MySpace, Second Life or Twitter? If so, please describe the use of site(s), whether deposit or loan related products are promoted, and what controls the bank has initiated through policy and procedures”.

thanks, I can use that to inform managment.
