TC has now voted on this proposal, and came to no majority (2-2)
Here is some of the reasoning that TC members provided:
'I like being able to break it up as long as a total of 6 hours is offered'
'I think forcing people to make 2-hour slots gives easier arrangements because players will provide times they normally wouldn't play on'
'I don't think we should stop the minimum requirement , after all players are welcome to give one hour slots they just don't count towards the minimum'
'I think that giving the players the option to give one hour slots will help those who have trouble finding 2 hour slots, and that there will be negligible difference in making arrangements'
TC has now decided to open a poll on the topic. This does not mean that we will necessarily go with the opinion of the community, though it may assist in the re-vote.
