i dont remember signing any thing . Just put my name down and filled in a survey of my knowledge skills and interests.
Then I got an email to say I was invited to participate. I was told to do a speed test and submit it and wait until the trial was over to fill out a survay
I did not get sent a dedicated email address or phone number.
