I got one too! Thanks for the heads up ltd, and the instructions on how to submit it. :smile:

It was my very first prime ever, I submitted it according to all the instructions, and 2 hours later the status was "proven", with direct entrance to #280 on the list.

There are only 122 k's remaining for Riesel base 5. Your Riesel stats page at [URL]http://www.sr5.psp-project.de/r5stats.html[/URL] shows 125 k's remaining. Apparently the last 3 primes have not been reflected. I'm assuming that someone needs to manually update that.

I mention this because it might make a new person wonder if tests are being handed out for k's that already have primes.

The Sierp stats page looks correct.

I see nobody is working on the table/db to exclude all new founds. Its better to combine both tables to primegrid.

Can you provide a link to the correct k's remaining? I need an updated link so that I can provide it on the Conjectures 'R Us pages for base 5.
