I am creating a membership site that has lots of info and terminology on it. I'm looking for a plugin that will let you build a dictionary so that whenever X word is used people can hover over it to see the definition. I know that this exists for forums but I'm not sure about WP. Tried to do a search on the plugins page but didn't have much luck - maybe because I wasn't searching for the right words. Thought someone might have a suggestion. Thanks!
