When writing a new entry with a goal on 43 Things I often like to refer to a place that I’ve visited or something that I have consumed. I love the simplicity of using a tag in my post to refer to something on one of the other sites, but I keep forgetting the syntax. If the syntax was in the “formatting codes” section it would help, but being able to look it up would be good as well. Even better would be a sidebar or a popup that would have recent things consumed, places, entries, etc.
