I signed up yesterday and the day before and I never received an event saying that I had been partnered with someone...

Did you return to the first page to see if you could send gifts? Sometimes you get partnered up with someone right away and don't need to wait.

Actually, it is letting me send gifts, but since I received Nada for these last 2 times, I thought nobody had partnered with me. Thank you for pointing that out to me.
