Very cool!

I was wondering what ever happened to 2,716+. I've noticed that several of these factorizations have been announced in this forum, but the NFSNET website doesn't mention them. It would be nice, from the viewpoint of attracting participants, to get that site up-to-date.

You are quite correct. Someone else made the same point to me in email.

I'll have a word with our web master.

I have to postpone the updates for the website for another two days due to personal reasons...
