Text snippets, a truly great idea and possibly an original. You post, but there may be a line or paragraph of text you'd like to add quite often e.g. 'Vote now on your favourite post' or 'please add a comment by clicking the link below. You know the sort of thing.
Create text snippets, and when you post click a link 'insert text snippet' and select a number (named file?) for the snippet you want to include. Great timesaver.
