I'd also like these donations to be authenticated, but I'm willing to wait if necessary. Here's step 2, including the new "ETA" part, from my original comment:

In your donation's "Public Comment" field, include both a link to your reply to this thread and a note asking for a Singularity Institute employee to kindly follow that link and post a response saying that you donated. ETA: Step 2 didn't work for me, so I don't expect it to work for you. For now, I'll just believe you if you say you've donated. If you would be convinced to donate by seeing evidence that I'm not lying, let me know and I'll get you some.

Would you be willing to match my third $60 if I could give you better evidence that I actually matched the first two? If so, I'll try to get some.
