In Tikwiki 1.10, all these actions are already logged
Do we need to collect image view and file view and blogs view/replies?

In most of the case, we must define if we consider the last editor or the creator of the objects

The resuls will be displayed as 2 tables users/users . One table for reads, and one table for replied. Each cell will contains the number of actions that occured from user a to user b.

TikiWiki is missing the notion of object. We can't use a join to find all the second author of an action
question
- do we use a join for each type of object to retrieve the second user
- do we save in actionlog this second user
