Braggadar: I'd say in the case of a starred game nomination if they don't officially confirm before the draw happens then they don't have a ticket ... and instead they should just personally message the user to tell them a draw is on and let them enter themselves for it.
I would agree with this. If nominations are accepted for the draw, then the person must accept before the draw deadline or not be included. Even with a nomination a PM will need to be sent to inform the person, so one might as well just tell them about the draw and let them enter for themself.
If the draws are liked and continue, then I also like the 48-72 hour draw deadlines. As can be seen in the thread there are several community members who are entering in a draw after the 24 hour mark. Often GOG community members can be active and helpful without being obsessive about checking in multiple times a day. The 48-72 hour limit seems more fair. Actually, another way to look at these draws are like a mini Doc-fightclub arena, without the imaginative scenes - unless BenKii wants to spice up and narrate his (holodeck?) dice rolls! ;)
