What makes you think that Loeh and Harvey read this forum?
Hint: instead, just email them!

Does anyone know if the lists are still actively maintained? And is the search organized in any way? PG has a generalized C/W project, but it only covers bases up to 140 or so. Where did the others originate from?
What does it matter if they use gmail? Fortunately email is from the golden days of internet when protocols were open standards and any email provider accepts mail from any other. Imagine instant messaging to be like that.

The searches are only coordinated from the perspective the they track reservations and completed ranges from individuals that communicate with them. They do not set up servers (BOINC or PRPNet) for outsiders to access and participate. PrimeGrid is only searching bases (to a limit) with no known prime because those bases are interesting. You need to remember that people set up websites for searches like this because it interests them. If Günter and Steven are no longer interested in hosting the pages, then someone else can take ownership and coordinate continued searching for GCW primes. Steven's last post to this forum is at the same time of his last update to his website. I have no idea what his status is. I have no biographical information on him. Günter is 76 (per his website) with no updates in nearly a year. I have no idea what his status is either.

My Wiki got the possibility to create pages for (Near/Generalized) Cullen/Woodall search with reserving any base by a user.
For now there're only a few pages done including history taken from those pages mentioned above. There're also pages for PG Gen.Cullen and PG Cullen searches, the Woodall page is not yet created but base 2 is reserved by PG, too. Any base can be created with own page using special templates for them.
