Recently, Russell McCutcheon asked on Facebook whether SBL members should be limited to one slot on the program, in order to make room for more participation especially among non-tenured scholars. That's not a bad idea, especially if a member could make more than one proposal and have only one accepted. As it is, I feel pressure to submit two proposals to increase my chances of getting on the program, since I only get full funding if I am presenting (not moderating).
That said, in general I would like to see students presenting at regional meetings rather than the annual meeting, unless they are very far along in their process. This is how things were before this crazy job situation came along, and my perception is that it raised the quality of both the regionals as well as the annual meeting.
