Thanks Jeff, that seems like a good 1st step. I need to also give them a reason why they have to click the link and create an account.
I was thinking that perhaps i can generate a QR code/or normal code, and send it to all new members via a message within Discourse. The issues with that are 1) is it possible/practical? 2) what about users who sign up the normal way.. can i give an invite link that automatically adds them to a team, or gives them a specific user level?
for other readers, if i/we can find a solution then this would be a fantastically powerful way to channel users into your forum
