Keep talking after a mentor says yes

Accepting a request used to be where the product stopped. The mentor could read what you asked for and say yes, and then there was nowhere to go: no way to reply, and nothing on the page that led anywhere.

There is now a conversation attached to every accepted request. Mentors open it from their inbox, mentees from their own requests page, and both sides see the same thread. When someone posts a message the other person gets a notification, and the email it sends can be replied to directly.

If a thread is empty it now says so, rather than showing a blank space that looked like something had failed to load. We also corrected a line on the mentee's page that told people to reply to the acceptance email. That particular email did not reach anyone, and only message emails do.
