We could detect the username of users logged in wordpress, joomla, drupal, popular CMS here. By reading cookie matching a name and looking in the value, we can see the username and set as custom variable automatically.
This would be useful!
would be also very interesting for magento e.g. small shops with only some but often returning vistors/customers...
1) it woudl be disabled by default
2) It would be only set if there is an empty slot (as scope=visit)
3) it's easier to implement it once in the piwik.js rather than have 10 plugins each implement the cookie reading + custom var setting (so, IMO it's more realistic / easier to do it in core).
I've looked for addon like this. i need there's seen visitors' usernames of my forum
It would be great If that addon is for Vbulletin forum (for example, most popular version is 3.8.7)
