i suggest mybb team to create a cms system
That won't be happening. We've said that many times before. We develop forum software, not CMSs.
You might try the Page Manager plugin if you want additional pages.
if you want CMS,you can use Joomla or Wordpress which are the best CMS available.
The greater power will be within a better ability to integrate users. The 2.0 api should allow for this. Once you have the logins integrated the rest is just visual stuff
I don't see MyBB turning into a CMS. Instead, I see potential for MyBB authenticating against another source, or a different source authenticating against MyBB.
Maybe with 2.0 we can get an offical bridge worked on by both teams at another already established CMS?
