There's probably a way to do this but if so, I read right past it. Here's what I'm wondering about.
Let's say I really liked a picture and gave it an acorn. Maybe the same day, maybe the next, or just whenever, I might get a tree-mail thanking me for the acorn. (Unnecessary but nice.) The problem is that I often don't remember the picture in question, especially if it was posted by a member who is new to me. Is there a way to find where I tossed the acorn?
