Re conference call

I would like to start a poetry reading group on the campus in the gardens. There are small shelters there, near a babbling stream (OK so it is artificial, but you can't win them all). Maybe those interested could meet with some tea or coffee and read and listen. However as Robbie pointed out we are all busy. SKYPE has a conference call system. Maybe interested parties should try this as well. I have used SKYPE for years but never used that function. Can anybody throw light on it ?
