1. I think we are not alone. I think we may yet find microbial life on Mars or Europa and evidence indicating life in other solar systems.
2. I think we should send our own signal for others to find -- I don't think it needs to say much except that we are here.
3. My computer has the time and it is a neat concept to put several computers to work in this way - I wonder why more projects of this type aren't out there....
