We have to settle on something or nothing is ever going to get run :P And this definitely will not be the only event of its type - if some folks cannot make it to this one, perhaps we'll simply hold another on the next available day.
So! Let's run two! Pick the one that will work the most for you, weekday or weekend, and hope to see you there.
1. Friday, September 1st 20GMT
2. Saturday, September 2nd 20GMT
Going for 20GMT on both dates as it seems to be the best type out of what's been posted so far.
