I am presenting at ATS during the thematic poster session on May 17th. The session is scheduled from 9:15am - 4:15pm and we are required to be by our posters from 11:30am-1:15pm. My question is when should I be putting up my poster? Should I get there before 9:15am to set it up or is it okay to put it up later (but before 11:30am of course)? First conference so unsure what the protocol is! Thanks!
