Which is the best module to view activity stream ?

Dear Drupal gurus,

This is pertaining to the site www.dentistrytoday.info (mode in drupal 6.34).

I want to install a module to show the activity log (activity stream) on the home page. The log could be as fallows.

Please let me know which is the best module for the same.

The activity feed could be as follows:

 XYZ (This is a link) registration was approved by site admin. View profile.

 User XYZ (link to user profile) is viewing topic ABC (ABC will link to topic)

 User XYZ (link to user profile) commented on topic ABC. (ABC will link to topic)

View comment. View user XYZ’s (This is a link) other posts

 User XYZ (This is a link) updated his avatar photo. View profile

 A user from ABC (name of the region) is brewing thread XYZ (ABC will link to topic)

 User XYZ (link to user profile) likes thread ABC (ABC will link to topic)

User ABC liked thread XYZ. ( Please note that till date I have not added like button module to the forums.)

Hope to see a lot of responses and many thanks in advance for the same.

Regards,

Dr. Veerendra Darakh
