He also lists an entry in the "About Me" section:
My name is Sam Thomas. I used to work for Oceanic Airlines as an IT technician. My partner Sonya also worked for Oceanic. She was a flight attendant. Sonya was aboard Flight 815 when it...disappeared? I need to know what happened. I’ve had enough of waiting until it’s too late. After Oceanic decided to abandon the search for 815 I had to find the answers for myself and for Sonya. Go to http://www.find815.com/ to help me find the answers.
The internet connection out here is really dodgy. I'm adding you when I can. I think I've come on a wild goose chase but I'm stuck here for now. I'll stay alert just in case and it'd be great if you do the same. Between us we might solve this mystery.
