-I like the idea of the 'Resume' that some one said. After all otakon is a large con, so if some one is new to doing panels or public speaking in general then they should try smaller venues first.
-I think pre-reg is more then enough of a deposit. Some cons dont even reimburse you that money.
- Evaluating is a good idea. They do it at schools and other meetings. Not to realy evalute wether they liked the panel but more on technicall things, like was the audence seemed realy interested and interactive? Did the panelist had more then enough material for the block that they requested?
