@sogo7 Well, in this case I wouldn't have had the choice either way: I am a guest of this department, and honestly it's nice for them to go to the effort of doing a poster at all. Doesn't usually happen for such minor folk as myself!
But thanks for the apology, and for the kind offer. I don't think the talk in that poster is being videoed, but I'm doing another one that is being recorded -- so if you're interested in the topic, keep 'em peeled. :)
