Wow! That makes three Woodalls in one year (actually less than 1 year), although this is the first Woodall found by PrimeGrid. Now if they could only find the next Cullen...
BTW, this thread should probably be moved to the Prime Cullen Prime project area. Is there a page on PrimeGrid that gives the current search status for Cullens and/or Woodalls?

The front page (first URL) top section shows "Available" tests. The second page shows rangewise split (3rd line from the top and last two lines at the bottom), though it is not obvious whether it is cullen, woodall or both

Exactly my point. Maybe I'm expecting too much, but I think that the stats for the Sierinski/Riesel base 5 project are easier to understand.

Thanks for the greetings :)
Currently we are not running any Cullen work. We hope to start with Cullens in the end of next week. I also have plans to improve statistics  the page was meant for TPS, and was only slightly adapted to show C/W, too. The limiting factor is time...

The above is the number listed on the page. I was confused at first, since a Woodall is supposed to be n*2^n1, but then I got out my calculator and found the equivalent equation 2013992*2^20139921.

Another one found, as hinted here and reported here.
Currently undergoing verification, slotting in at #25 on Top 5000 list. The proper form is 2367906*2^23679061. Will the next one be a megadigit prime?
