When you first sign into Uservoice forum it seems a bit dodgy as the warning tells you it's not part of Twitch which is confusing -

For example I got a link this morning from a charity asking me to vote for their charity on Twitch - I went to vote and when I tried to vote it said do you want to allow access to Uservoice - Uservoice is not part of Twitch.

Of course this caused confusion and having looked into it I realised it wasn't some kind of scam link (as being not part of Twitch had alarm bells ringing) and the url isn't even part of the Twitch domain - it's Uservoice.com. But it could be made more clearer that Uservoice is Twitch.
