MyBB Community Forums

I was wondering how to get my mybb forum into search engines? Can any 1 help?

It's not something that anybody can 'make' happen. Google will crawl your forum and index pages over time. Make sure you've got some good content so it actually has something to crawl, and maybe use a plugin like Google SEO to rewrite URLs and generate a sitemap.

use this to optimize crawlings:
http://www.google.com/webmasters/

If you haven't added your site to the webmaster tools then you should (essentially you tell google about your site)

http://www.google.com/webmasters/

as well as yahoo
http://siteexplorer.search.yahoo.com/

and bing
