Sorry if this has been asked a lot, but I did several searches amounting to nothing. I have seen some posters remark on the laps completed by other posters and wondered how they got this information.

Log in using your web password and you can view all sorts of stats. On the forum you can click the little stopwatch and graph icon below people's post count and you will automatically view their stats.

While in game you can always use these commands:

*Type T to bring in the chat/command thingie*

/w laps (will display your laps on that combo)
/w distance (will display all your travelled distance on your online license)

And you can always use that to see others' people stats too.
For exemple.

/w Davo laps (will show you how many laps he did on this combo)
/w Davo distance (will show all his travelled distance)

and so on...

You can even extend that further Meanie:

you can go /ws <Track> <Car> <command> <user>, to get descriptive stats and get stats from anywhere and anyone, even when not on track.
