"The SMS record store anyone can edit."
In a nutshell: separate the content from the page name with a space, leave out content to request the current page
A local weather expert in the villiage of Wikitambe would like to publish the current temperature on the public wiki.
123->811: "temp/wikitambe 26 deg"
A client would like to read the current temperature in Wikitambe.
456->811: "temp/wikitambe"
811->456: "26 deg 123/30m"
The client has learned that "123" posted "26 deg" 30 minutes ago.
