It isn't possible for non-site-admins to edit pages (since that would require them to have access to the admin backend for your site). We have discussed the idea of making the "quick edit" functionality available to specified users (rather than just to admins) though as yet this too isn't possible.

You can, however, set up different users as contributors to the forums/weblog/photo album etc in order for people to be able to contribute to your site without being an administrator.

Thanks
