So you want posts of both post_type "post" and post_type "group" to be
included together? Then I would use the 'posts_where' filter to call
back a function where a regular expression replaces post_type = 'post'
with (post_type = 'post' OR post_type = 'group').

To keep the admin area from being affected, just test with
"is_admin()" before applying the filter.
