I can make it every sunday and on most saturdays. The time is fine for me.
But I can't take part in testing every saturday. That's whensoever our dart-team has got a game in our local dart league.
This weekend there's a dart tournament on saturday, but I'm not sure at the moment if I'll participate. So maybe I'll take part in testing the SA on saturday.
In any case I like the idea of weekly test sessions
