So the results are in and it looks (unsurprisingly) that the most popular time is Tuesday at around 18:00. Probably too late to get anything arranged for this Tuesday, but will look to do something from next week onwards.
Picking courses randomly worked really well last time (there's a guarantee that it won't this time!) so I'm going to try and do the same again this time. The next six people to post on here, add in a number between 1 and 168 at the end of your post and we'll see what we end up with - if we end up with some that are very similar to each other, then I might pick one that's different, but hopefully not.
