there, i have a question regarding this plugin. I only want

Hi there, i have a question regarding this plugin. I only want chat to be accessed via buddypress groups. I have configured this. But what i want to know is how this plugins polls the server for updates.

If i had a single group with 2 members within, both members had previously accessed the chat but since logged-out - does this plugin keep polling the server if there are no users actively logged in and on the chat page?
