The systerserver was a Linux server run by women.
We got to a stage where we didn't want to rely on the (very supportive mind you) guys hosting our website. We wanted to Do It Ourselves. So this was our own space to practice being systems administrators, where peers are present to answer questions and show by example. We met on an IRC channel to talk shop. Then one by one take on a task that needed to be done or learnt. The women are from all over the world: St. John's, San Francisco, New York, Montevideo, Madrid, Amsterdam, and further.
