I have set your plugin to only log: login, login fails and profile edits.
In the log, up to 8 CONNECT activities per user show up in a period of 1-2 minutes?
Additionally for some CONNECT activities, the user's first and last name are shown instead of his loginname?
I am using WP 3.2.1 and also the following plugins: theme-my-login, user-access-manager
Any idea what could be causing this strange behaviour? Is your plugin picking up something else as CONNECT activity?
