How to set up meetings in IRC

Hi Everyone,

I thought some people might find it useful to have instructions on how to
use IRC to facilitate PBG meetings, so I've put them on the PBG wiki:

Let me know if you have any questions, clarifications, or improvements.
Feel free to edit directly, or ask me to make changes.

Thanks!
