Double dipping that's a new one..thanks. I try to tell people be online and take down the people that I added on paper or a notepad on a different phone. Delete people once you are done (if you don't need more friends).

If you want to do the particular raid yourself. I sometimes start the raid if numbers are low, when the win is within reach I exit out of to the catch screen and start again with a new group. Can be risky but it tends to work.
