I figure I will risk flames and just post this..
I would like to see a way to send journal entries from cell phone text messaging.
Obviously, this will require 2 major things.
1: security setup
2: gateway to post to.
Security could be done by simply sending a random auth code to the cell phone and then entering that code once recieved.
As for a gateway, a special email address could be created that will post the message, using default journal settings.
On the security side of that, I would suggest a random code generator create a 8 to 10 digit alpha-numeric email addy unique to the user.
Obviously, this type of service would be for paying customers. Just a thought, cuz I know when I am out there are certain things I would post.. "IF I ONLY HAD A WAY!!" :)
