Ever want to send an SMS to someone but worried it won't be saved for litigious purposed. My god you're creepy. But someone still has a free website to help you out.

My Mobile Witness allows you to send them any text or picture messages, and they'll save it, along with the time/date stamp in their virtual vault.

Meaning aside from just saving your text messages; you could also take a cell phone picture of something and save it in their vault as evidence.

(Law enforcement personnel, once verified will be granted instant access to the info on the site.) 

Of course more often, this site will just be used by brothers and sisters to rat each other other; but you can still check it out here.
