I just approved this post to Classifieds:

https://choralnet.org/classifieds/huge-ttbb-collection-for-sale-cheap/

without checking to see if the link in the post worked. It doesn’t, so I wanted to send a message to the poster, but I can find no trace of him. I now see that when a Classified or Announcement post goes up, the name of the poster vanishes. Am I just not seeing it? Is there somewhere to find it that I don’t know about? If I just leave a comment to the post, will the poster receive it via email?
