Related entry post form needs a reference to the existing entry
I also made a "related entry" post. I had noticed this before, but when I clicked on it, it didn't give any hint that it was going to show that the entry was related to the one you were trying to relate to. If the entry box would show the related entry text, people might actually use it, and it could become useful.
1. click on an entry
2. next click on "Post related entry". This brings you to a page that looks identical to the "New Entry" page. It would be good to add the content of the original entry here.
