I have no problem starting later, when everybody is ready. I just put in 7pm to emphasize that we should start as early as possible, to have as much time as possible. Now about the participants, it would be advantageous for them to have as many evenings free as possible, in case we have to rerun the whole thing. I wouldn’t like to stop because of time restrictions. I guess we’re set with mattiejas and kassz, but the fourth person should preferably be someone who can participate on several evenings. To let someone else participate who hasn’t done it before would be nice as well, so we could wait until the beginning of the next week to decide.
