Okay, Ken. But since you are a "Hero Member", I expect that you should know these things.
Posters name is directly below title info, above cover art (picture). It's best to thank the poster on post, especially when she's been attacked by a troll. Give her some stars.

She won't see the thanks here, unless she'd commented on your post. But goodd on you for thanking her.
The reason you can't see the Green Tick is because I had already moved this to Fulfilled (archived it). You should see it on any post you have (or will) started.
Enjoy your book, and I'll see you around.
