How do you cite information gleaned from Facebook using FTM? (find, person)

[peppermint]

Please forgive me if this question has been answered before. I currently use FTM 2011, and sometimes the source templates confuse me. Very often I find out about distant cousins having babies or getting married via Facebook, and I'm just wondering how I should cite it. Do I use the Digital Archive template? the Personal Knowledge template? the Email template? I'm lost. Maybe it doesn't matter as long as I'm consistent?

Any thoughts are helpful. Thanks!

Personal knowledge?

I don't really know FTM or their templates, but would think that the closest to it would be email. It's essentially a message via the internet.
