Evermore is a great little plugin and will save you time when you post. It automatically puts in the more tag for you at a preset setting that you choose. I think the default is too small and doesn’t show enough of your post for SEO purposes so I change the settings to 2 paragraphs and 250 characters. I’ve found this to be better than the default 1 paragraph and 100 characters.
Abbreviate all posts when viewed on multiple post pages. This makes all posts behave as if there is a “more†tag at an appropriate spot inside the content. By Bennett McElwee.
