Is it correct? > I have not tried the cron myself, but it just seems like a standard cron, which calls your bot regularly, independently from any Wave modification, so it makes sense that it gets called only once every period of time. > 2.

I think you should be able to access a wave by its ID. Regards Raphaël -- You received this message because you are subscribed to the Google Groups "Google Wave API" group.
