If you are keen to help but can't become an editor, here are two suggestions:
- Review categories from the public side and provide a list of non-functioning URLs or sites whose content seems to have changed. If possible, track down a new url for the sites. Use the update feature (for each url) to report problems, or get in contact with a local editor who can act on your reports.
- Find good urls for categories and submit them with good titles and descriptions. If you are heavily active in an area (like adding 20 sites to a smallish category, or 100 to a large one), you can email an editor to let them know. They'll eventually get processed anyway even if you don't notify someone.
Good luck! <img src="/images/icons/smile.gif" alt="" />
