I needed help understanding Iris...and so I went to the iris forum. 20 people really helped me. Great advice. Long thoughtful answers. Great forum. When I established my beds..( with confidence) .I went back and collected the name of every person who helped me and sat down ..found their post to me that I liked/ appreciated..and gave each one an acorn in that post. I did it one after the other...one sitting. On the home page, it showed my acorn gift -- but just to one of those folks. Later on I believe I saw that I gifted another.. I know the entire session giving acorns were completed because 20 acorns were deducted from ny balance. I never received one thank you..which .I thought was odd..since it was 20 people. And so I wondered if actually delivered. But now at least I understand the process of the "who gifted an acorn" area and why I did not see all the tips I sent. It did not matter to me that my tips did not post as given, but that is a way for the giver to see the gifting took. Now I know ( then I did not ) that I can actually see the acorn gift showing in the post in which it was given. Click on the acorn number and a list of the the givers names appear.. Neat function. Thumbs up works that way too.
