I can't find anywhere in the user guide that explains what the symbols mean. On my posting of "From MRI to now" I have a Star, a blue thing, and an envelope. What do those things represent? I understand what "M" means, but what does the red magnet or horseshoe looking thing mean ? Or where can I go in the website to get an explanation of the symbols?

I apologize if this is common knowledge to a lot of you.
