So, the old DearDiary had the concept of an 'entry footer'. I prefer the term 'entry signature' these days, but what's people's thoughts?
My idea for this as a concept is that you would use the editor (i.e. the one you write an entry with) to create this signature and it would be automatically appended to the entry content within the editor itself. That way, if you didn't want it on a particular entry, you simply delete it. Or you could edit it like any other part of your entry - it's just automatically populated for you so you don't need to keep typing it each time?
Thoughts? :)
