I've recently launched a forum in my local community but Google has yet to crawl any of the pages so that a search for the content within it will be found in search engine results.
Does anyone know why this could be an issue? They have crawled all 65 pages on the site but have not crawled the forum which make up a much larger part of the content on the site. The forum has been active for 3 weeks now and Google has been crawling the main site about every week.

Thanks for any advice!
