Doubles is simple, you and your partner just send your singles points as usual, and they will be added up to make your doubles points. For now Doubles will only be played at Masters Series and Grand Slams.
Here everyone can make permanent doubles teams, or if you want you can change partners every week. Though it would be easier for me and Rik ( tennis2006 ) if you played with the same person every tournament.
** I will play doubles too, so everyone has to send their points to Rik ( tennis2006 ) as usual, and he will forward me the results.
