Social media is very fast moving and tweets and posts can often get lost. To help us achieve maximum impact, Thunderclap schedules the same message across Twitter, Facebook and Tumblr from everyone who signs up at exactly the same time. To join this online flashmob all you have to do is choose the platform you want your message to be on and come 7th February at 8.30 am the message will go out to inspire people to get involved in Safer Internet Day 2017!
