I think a really cool idea would be to allow us forum-goers to supply the hints every Thursday. HMX or the mods can select a different person each week to give hints in the prediction thread. The person who holds that responsibility can do no more than 3-4 hints or something along those lines. This would get the forum community more involved in the process while also allowing those who get to give the hints a chance to show off their creativity.
I like the idea of a mod or HMXHenry starting the prediction thread each week because this allows them to announce who will be giving the hints that Thursday. This way we know for sure who is giving the actual hints, rather than someone just saying "hey, I'm doing the hints this week", and that person goes and feeds us a bunch of red herring.
I don't know what the selection process would be for choosing a person each week. I don't think Henry or the mods want their inboxes flooded with "oooohh pick me this week, please!". Just an idea to help get hints back into our Thursday predictions.
