Hi Sheffield and Nathan!
Would love to have you join us! Just so everyone knows, I'm not picturing any limit to the number of people we can have on the panel. 3 person panel? Great! 8 person panel? No problem. The more people we have, the more diverse perspectives we can represent, for example from a high school student as you mentioned Nathan. There also may be something of a "meet and greet a Wikipedian" time at the end, so even if you don't want to sit on an "official panel" in the front of the room, you could wear a badge or name tag that lets people know they can come up and talk to you.
No new info from the library at this time, but I'll update you all when I hear back and we have more detailed plans.
Thanks everyone,
-Travis
