Virtualmeet.net is a website I just stumbled across which basically organises powerlifting contests – all done online. There are male and female categories, and quite a few women have entered so far.
From their website: Virtualmeet.net stages drug-free RAW global power- and weightlifting meets with near simultaneous lifting venues around the world. Participants lift at their own gyms and upload video footage of their lifts for judging. The results are adjusted by weight and age to allow everyone to compete together; the only classes that exist are those for men and women.
