What have you changed?
First I thought I was banned or something,
then I thought it was my new skype phone installation that had changed my security settings. Well, I have uninstalled my phone, turned off my firewall, set all my security settings to "low", made mumsnet a trusted site, disabled keyword filter, and mumsnet is still not passing my security. What have you done! Help! I want to rewind 3-4 days and be able to browse threads, post and reply without having to restart and fiddle about with my security settings, it is driving me MAD!!!
