HELP HELP!! Ive forgoten...
How to record battles in stw.

could some 1 tell me what the extention is please.

I had A VERY good game vs drifta Yesterday.
(best game ever)
That would heve been one of the best battles ever recorded IMHO
.
600+ kills to 600+ kills.
Was drifta winning then it was me winning then it was drifta winning. then i was winning.
Then there was a bit of a mele.
Where we both were loosing.
But i thought drifta was going to take it.
And i finaly came out the victor.

(then i was beaten 2 times in a row, But thats not the point)

the point is I really want to start recording these battles.
And i just dont remember what the extention is to get the game to record them.

Help plz...
