Dear Mumsnet
Your 'tech support' (ha) have taken you for a ride. This site's security response to the Heartbleed exposure ( heartbleed.com/ ) has been woeful and anyone with slightest know-how of OpenSSL has been able to grab the logging-in details of Mumsnet users (including administrators). I could post screencaps of the board where this geezer has been posting up how funny he is messing around with mumsnet but that's by the by.
This is especially dire news if you've been daft enough to use the same password for mumsnet as you had for your email addresses and amazon accounts etc.
Change all your passwords immediately, ESPECIALLY if your mumsnet password is one you foolishly use for other services.
Finally I urge you to reconsider whether this website and its administrators take your security seriously.
