mySociety, the creator of various digital tools for citizens enabling them to take action, has announced that it is retiring several projects this year.
Pledgebank, where individuals can pledge to do something if others help, will stop accepting new pledges in February. Users will still be able to sign up for existing ones until the end of June, when the site will close.
FixMyTransport, HearFromYourMP and ScenicOrNot are also being retired, unless someone comes forward to take one over. See https://www.mysociety.org/2015/01/28/goodbye-to-some-old-friends/.
