To show Classifieds Ads in buddypress activity stream


1. Created bp-custom.php and added as what mentioned in the link:

Uploaded bp-custom.php in plugins folder so that it loads before buddypress

created a test ad with classified. But that does not show in the activity stream of buddypress. Anything i am missing

2. also is it possible to have multisite where
site 1 - buddypress
site 2 - classifieds
site 3 - directory etc.,

where when users posts ads fro site 2, the ads can get displayed in activity stream of site1.
