Moderation
From next week I will not have frequent internet access, so if anyone is interested in taking over as moderator then you are welcome. I don't have any scripts for maintaining the project data, I have just done it by hand, but there is not a lot of work, and after the easy primes are found it the amount of work involved will decrease.
A new moderator would need to copy of the files at http://www.geocities.com/g_w_reynolds/Sierpinski5/ and http://www.geocities.com/g_w_reynolds/Riesel5 to somewhere they have write access, and contact Xyzzy for moderator status to be able to edit the reservation threads. I am going to pack my life into a bicycle trailer and spend the next six months or so on the road or tramping through our national parks. I will log on from internet cafes when I get the chance, but I don't expect to spend a lot of time online. Keep posting your results, even if nobody picks up the moderation duties I will eventually get back to it. Good luck with the search. Geoff. |

I am so jealous. What I would do with 6 months of the open air life. Sigh!
All the best and stay safe! Regards Robert Smith |
