Great names! I have been rethinking the butterfly name because even though it is subtle, it doesn't really say what the club is.
I really like the Giving Project and the Joy Project. There are some other names suggested that I also like but are also taken. Some of them are exactly the same but are associated with different groups in different states so I wonder if it matters if someone else has the name, or if I should register it. I think name registration is state-specific. On the other hand, I would like it to be original and not come up with anyone else on a google search.
