Accepting a sitting request

I shared a sitting need with one specific member of my village, but she (or I) couldn't find a place for her to accept/fill my need. She could leave a comment on my need, but there wasn't a place to click for her to offer to fill the need. 

It was today, and she sat for me, but I would really like to give her points for it. Let me know what I can do. Thanks!
