"Want to stay safe but don't want to bother people by always telling them your plans? Use LetSomebodyknow.com to quickly log your plans and have the choice of only notifying people about them if you don't return."
or should that be 'going somewhere you shouldn't be and don't want to tell anyone... but just incase you dont come back they will know where to look?'
Joking aside, it is very important to let someone (or a website) know your travel plans, your expected locations with date/times and your expected return date/time. Be safe, be happy.
