So I've been seeing this question pop up a lot, so I thought I'd just make a quick guide on it for all those who need it.
To send points, first go to the person you want to send points' profile and click the little gear in the bottom-right corner of their banner.
Then click the "Send Points" option.
Type in your username and password, then click "Send Points".
And thats pretty much is.
Thanks for reading. Hope this helped.
