UserVoice has a "trusted" argument in their SSO arguments:
As I understand, this allows users to be logged in into their currently existing accounts, something that would prevent duplicated accounts (SSO and UserEcho) that currently happen and require a manual support ticket to be merged.
Is there any reason why UserEcho couldn't (or wouldn't) support this "trusted" argument?. It would be, of course, a feature enabled only for forums running on their custom domains (to avoid security issues). I think it would be a very welcome feature since dealing with duplicate (SSO/UE) accounts is quite a pain.
