It has no connection with IP Board at all other than a link to it. Despite the person you wish to chat with is on the forum there is no way to invite him to chat from IP Chat. It is "Standalone" with very limited functionality.

There is no personal information gathered by IPB software.
Should anything that IPB does collect at the moment fall foul in the slightest way of a European Directive what do you think is going to happen?

Get serious and talk about something else, more time than it is worth has already been spent on this non topic.
