This site was set up in 2008, to help people find Government consultations more easily, and to show that it could be done: quickly and easily. The site has never been funded as such, and has relied on volunteers for maintenance and support. It hasn't had much maintenance recently and this shows: some consultations can't be found and some functions don't work as they should. We are currently seeking funding for a new version of TellThemWhatYouThink.
In the meantime, you can search a limited number of departments for open consultations at the Directgov Consultation Finder.
