To add a directory to dmole simply browse to the most suitable category trying to be as specific as possible. For example if your directory is about local business in England, navigate down to the England category rather than placing in the UK category.
If submissions are allowed in your chosen category an "add site" button and link will be available next to the search button and at the bottom of the page.
Fill out the form ensuring that the details are correct. Use plain English and avoid sales speak. For example don't say the following unless you are DMOZ:
"The best and biggest resource on the web"
Phrase the listing in the third person. For example:
"Gimpsy is a directory that classifies websites by the service that a site provides."
