I'll answer the questions, but others, including Raistlin and the staff, will probably have a different idea from me.
1) Everyone is free to nominate anyone for the hall of fame, it is the committee's job, using several criterias.
2) Hopefully, it will. I don't know for sure, but Raistlin told me that several staffers like the idea. Maybe the thread will get a sticky, maybe it won't, that's up to the staff to decide.
3) Of course, 9 members is the starting point for the committee. Depending on what happens in the future, we may replace members, or add several more.
