I just signed up here (finally found out where the UK chowhounders had gone!) and noticed that at the moment all passwords are being transmitted to this site in plain text over HTTP, so everyone’s password is essentially compromised. It would be wise to use HTTPS for any communication involving credentials - this might just be the sign up and login page.
Anyone that used a routine password when they signed up that they share with other sites should consider changing it on on those other sites.
