Different groups hold meetings during the MPSA Annual Conference (e.g. Editorial Boards, Caucuses). The MPSA reviews requests and can assign times and a (virtual) room.
Often Departments or publishers host receptions during the conference. Virtual receptions work best if there is a theme:
"New Developments in...";
"How to finish your book during a pandemic" or
"Martini's and Monetary Policy".
Organize a focused networking event that brings together research on a specific topic, or perhaps attendees from a specific country. Don't be afraid to organize "fun" activities:
"Political Scientists & their Pets"
"Amazon Movie Night". Watch the same movie & chat.
Length. Either 15-minutes (the time between the sessions), or 90-minutes (the length of a panel).
Small Rooms. They hold just 10-12 people (plus a host) and work well for conversations.
Lectures. Large, topically oriented reception could start with a 15-minute talk, Q&A and then....
Multiple Small Rooms. Attendees select a small room for 20 minutes of networking before they move do different rooms for more.
