There are time limits to each live podcast session you create, though you can go live as many times as you'd like on any given day. You can get more live podcasting time by upgrading to our PRO plans:
Free Speech - 15 minutes per session, with at least an hour break in between each session
Broadcaster - 3 hours per session
Anchorman - 5 hours per session
Publisher - 5 hours per session (if you want to have that content archived) or choose unlimited live broadcasting (content will not be archived)
