Hi, I have a phpbb2 forum running on my site. When i set up my sitemap is it possible to have it index all posts left as i cant add them all and posts in the future cannot be added? Thanks
If you can get a mod for your forum that will generate a sitemap, that is usually the best thing to do. Alternatively you can use an external sitemap generator program. For more alternatives, you might want to check: http://code.google.com/sm_thirdparty.html
You'd better download a desktop version to make a sitemap for your forum. Most online sitemap generator has a limit of 1000 pages.
You can create two separate sitemaps for your site and forum and merge them manually. e.g. one sitemap for www.a.com/ and another for sitemap for www.a.com/forums/ and merge them
